2 2 in the the
the the the the the the the past anyone have you ever been to Cuba hold them jealous of their power of evolutionary that's and down there are some debates and our maybe also you question the how what what about the Internet and plans may be preventative so as to the internet and you back and that's what the next talk will be about arts and the incentive to want and determinant of civilians and and about these a while I'm welcoming allows for will and end and lateral few have something yeah so I and this is the use of this kind of all the way in which the end of the of the of the of auditing access and 1 axis of like you look at the time will I'm was stuck up here at the mission and the lord a college student fishermen union agreeing to work the right so what's what's that so when you look at what sort of
official Internet looks like in Cuba are the sort of place we are going to have to start
is a text which is the national telecom about new provider and also I P they've got a bunch of storefronts around around major cities and around the country on and for the 1st row short-term tourists so what what this looks like is you're going to
go by these cards are they come in 1 2 5 our denominations you scratch off the pain you find a Wi-Fi hotspot you enter this username and password and it gives you some access for a little bit yeah but for a reversal of citizens of Cuba who were living there they have something that you feel somewhat similar the don't have a longer term username and password account but with with the service called delta and they motor balance and the walk in with their their sort of term IDE whenever they go to get Internet yeah the and the Internet is of place you go
to and I think this may be sort of reflects again on what we are where you may have heard of in the open observatory talk yesterday that there is this sense of the internet as a place of this is not an uncommon sight to see in evenings is a bunch of people going to their local park which is where the Wi-Fi hotspot is to to get the internet for for the day so and that so this graph shows briefly
how the internet in the hot day local host boats in the water of the distributed this 1 slightly updated the newest 1 so it's not like 500 in a hot foot around the country right now but with this graph to correctly see what's kind of these 2 which and a half so for instance in liner there's the at the moment of these graph we made were 60 ones scintilla over there were 27 of these these hatchet enormous in each province augmented to appoint aging I wanna right now has like 200 photos something the like that you can check for more information in the Texas website on the spot to go a bit so the
prices of the Internet at the beginning wasn't exactly wrote the service of 2 years ago the price was of 2 CCs there in after a while the drop in the price 150 and right now the prices standing still 1 to see an our for some reference let's say once you see it's 1 interview into 1 American law or 1 you just put a sense on the amount of the price it takes a house plans of what to do lowered the price of these of discards in some point in the future even more so the 3rd
the point here right is this is still more expensive
than you might pay on an airplane flight but just as a another kind of references and those are quite sensitive to it so yeah so
what does small Wellington the looks like than in Cuba this is Ellen page 4 note what male so these assemblies they it takes a brought out roughly at the same time us denote a connectivity holds but things go came out of the word category link to you right now would they would to CrIII for most of the country and that's going well the price of borrowing 1 of these e-mails is of 1 to see Birmingham byte of data you get from your e-mail which is a lot to once again right and so the point here is that for most Cubans on your phone the data you get is not up to the internet even where you can just like load for insight on your phone what you get on your phone's data plan is access to e-mail at a dollar per megabyte of female transfer so so how does this compare to other foreigners who visit well
you may have seen that there's roaming agreements are those typically have been about 2 dollars per megabyte of internet but if you go with your T-Mobile SIM or another international arts and it often will roam onto a taxes data network but it will charge you about 2 dollars per megabyte to to get access to external internet and if you plan ahead there are ways to get a little bit better this thing called Digicel came out at you buy it through Amazon as the distributor that will give you some part of that is a prepaid you can get 100 made use of for up to a little bit more and this brings the cost down to about 25 cents for Magritte 20 cents for might even when you buy sort of these pork roaming prepaid plans that you find in a secondary market for these cards in Cuba where where people in Cuba who want to get a mobile data will find these cards imported you can keep recharging them once you have a card and so so getting this sort of external hard thing and that just being 1 of the more efficient ways to have cell based on the internet so the set besides the
sort of like the official way of chronic incurable Doppler primitives the 3 most common ones are epoch in which Wi-Fi cheering and some isolated networks good season the island right now so I'm sorry let's gave the let's see what each of these things is so that they get a similarly basically a college of 1 terabyte it feels its use a hard drive with wonder why different formation become the multimedia series TV show for every you may see on the Internet it gets collected during a week story a hard right and then resold information to people or on the CD 4 1 4 bytes the regions within 1 invites to seize the new halfway each sharing the most common up for that these they're called collective I will get to back to that dealer later and then this estimate which is how much information it will completely offline from the Internet I will get to that later as well so talking about
a pocketed the celebrated MAU so right now if you will to the world that you can see down there you can see what's going to be next week's spike at the inn of honor and I think you can all let the media well right knowledge is using the what's 1 of academics we so we highly encourage you to go with that site and see what kind of intermediate consumed by people also something that a it's near the site like there's not only 1 person that assembles the bucket several so information may change from 1 to in order to some extent right so there's not a single packet a that that that sort of arrived in the country each week and it's not like the entire disk is new content each week or rather is some delta of the new TV shows and movies that have come out to replace old ones but there is this sort of continually circulating set of disks on that that people use for both media transfer instead of each person individually like paying the amount of money that it would take to download that from the extremal Internet so what you see right is and that there's this sort of nominal prices that you can get if you go to a store but that also within groups you know that someone a friend will get 1 of these disks and then share with with their friends sort of all is 1 so that everyone gets their quota of media for public so were defined a pocket and
online it's fairly easy if you will plus a repair shop or route if you go to what place that looks like this 2nd photo word there's a person with a lot of want interviews mistakes there's probably a place where the pocket they sold for a quarter of on the formula 1 that's actually a really nice due to you we have the link down here it's the it talks about the pocket innermost year away they go in a b the pairs so if you want you can see that In own below so you're entitled Wi-Fi 5
so the price of the internet connection is high and this speed is not great either so you get up to 1 megabyte verse of the 2nd when you go to Texas why 5 in this is not good like you may be able to pull boy the maybe not really good video if you are going to do to streaming it's a possibility but not really great so people even though the speed sort of great people use to so for coal correct fight which we're going up to the Wi-Fi and then create and that In into the page in cell this connection to several users for a fraction of the price so you will basic in the bottom 1 may have it being distributed between 6 or 7 people at 1 point but difficulties cheaper people use that the option in India and there's also Steelers things going on so can I won't tell me what's wrong with that million page the not secure precisely so for a long time I think I didn't know about it should appears they had http period ending about as a beginning of this year I think there needs to be to the loading website for developed up but they forgot to add that to the login page 40 we use the primal for and that's always formed so people keep on putting routers the log afterward the semis I'd be making perfect also of these pages in euros to hearing people's accounts and that's what I like this I would only thing to do if you see anyone would police reported to authorities it how it's worth saying there also that
while there is a GPS now but in there there's still all heterogeneity here there are still plenty of hotels where you end up with what is actually legitimate attacks a connection and yet still the login page achieved uh it's not actually fully rolled out unfortunately yet so all will tried to tackle this problem 1 way so this we gave the recently released um news article in grammar 1 of their most important cone newspapers in a country which explains basically I know most of you probably don't think Spanish so as to it translates there's some problems with the certificate for decide ended selling you the user must not he continue and they're trying to show the people how to identify where site is secure so that's you know a plus 1 is not enough yet not good enough get so 1 Monday version
of like yet another sort of part of this whole picture but the the which are realized we went there to to see when that when I would give it to investigate and is this there's also this whole scope of institutional Internet out so if you are associated with the university or you've got your company you may well find that that entity has some sort of larger pipes that that has a state entity it has agreed with with the telecom to have that and with as as sort of a larger town and so for instance at the University of about there's there's a general type of Internet access that is available and the university itself then provides a quota system where all the various students and faculty get some access to that but it seemed like for the educational institutions and how they were doing that is that students get some quota over week month so maybe you can measure 800 makes a month of faculty would get a bit more so it's not a huge amount in general it in order to sort of the load of not a super big pipe over quite a few users but it provides this alternative where you see people strategizing lot where if you need a short term high-bandwidth thing you would go to 1 of the parks and pay for your our of Wi-Fi if you want to be on I A C over a longer time or something low-bandwidth out you would use your university connection which is needed in terms of how much rather than how long you're connected and so so that that demons of getting played a lot another example of that happening is that this informat system which is a dial-up connection that's available to the doctors and medical professionals on the for the cost of a phone call which is cheaper you get access to a bunch of educational sir and professional education material and also some limited access to the internet over that dialog call so there's there's these other systems that are both available to some fraction of individuals or to you know some locations that the of help are so provide more of this picture so I guess to to sort of add to that we found at
the University of Vermont is that it was connected to this larger system called red Universitaria that we don't care very much about this is that the the university network and and so what what that means in practice a what that translates to is that you're on the so at at the University of honor we were getting 10 . 6 of something of something internal addresses on the land that was the university and that was part of a larger land they connected a bunch of different universities and so if you go to the the right Universitaria page they they say they have 26 member entities are you find that that that network in practice that the routers are all in a 1 7 2 . 30 slash 16 but you can talk directly to these other 10 . something 16 prefixes and so you can send your traffic to other universities around the country without ever going out to the public internet so there's this intercountry land without and with is not going through an ataxic action but you're able to send much higher bandwidth traffic to other parts of the country but going against a also right if if I've got some scientific data transfer to another university but also you can start to imagine that this is how things like accounting data might transfer to another city so that that city starts to get the the media content that there are these places where these larger lines exists that order under this totally exorbitant prices so that's
all right our world student history there were over estimate so what streets that were how it came to be who we are who runs that work we're going to try to answer all these questions so to give you a little bit of background biking to sunset in 8 of gaming communities were started talking about and people started to do you know LAN parties spend it was kind of awkward to go to a LAN party with massive CRT monitor them you know the PC power in there is in so people decided to make something kind of 4 permanent for the some parties people decided to to roll the at wires to their friends houses by routers switches sorry and then have small atoms in the neighborhoods in that were great for a while but you know after a few moments of reading the same person over and over you might become tired and office and people started trying out all their so similar that work due to kilometres away from how can we connect to that in people started to white routers and started to connect all of these 3 really small networks into something that became masters and trust me when I say must if I think massive would be a proper word to describe it so instead right goes up to 100 thousand users In have thank you in the future is up to 100 thousand users in of an element in its fully disconnected from the Internet solo crime mole reduced normal thing it's an Internet of its sold than we want to show you guys some stuff we find it inside the net work so this is
that this is a fairly of all up there for those who have been to Cuba American natives Helena CD my hometown and that sealed spread map of this that garbage so you will have the py lots which at the moment of making this graph where only 5 there 9 pi lots and that's the approach to make goers right now at at that point in time sorry in right now is slightly the here so for instance that Harry of reliable its full recall where in general which is between the blue the portal and the black spot is fully chorus well in most of the highly dense not density populated areas are covered by this net work given a wider reach without using you know fy optic fibers or anything like that so it's use Wi-Fi in run-of-the-mill you to the gutsy cable basically told it together so as a result only 1 its
you can find his name is moving so because since flows and a speed to some canonical while is that of winter solid and the other Rio let there be say this CDs are not corrected between then the immigrated to the internet anyway and they're not necessarily known as ethnic and use using as a grain of cellular term to refer to the use of the grid networks ended you will see a link down there that link will explain what happened to the virtual 1st met in the other relations bodies life thing the outer world translated to English happily if you wish to de-link input and submit the request to the block yeah so here
in terms of like what we're looking at when we think about us now that we have these neighborhoods that sort of evolved and they they sort of end up with the central points that areas that are called pillars in the community and so pillar is generally both a person who is the person responsible for that neighborhood and also a place which is often their apartment or some other you know specific location that's got several computers a bunch of wireless antennas are some routers of each of these pillars is connected to at least 2 other pillars our and that and that forms the backbone of the network and then connects 2 nodes which are sort of in that neighborhood and often heard you know you the of those direct wireless thing or or maybe in some cases an Ethernet the nodes are a sort of you can think of is like the block level where it's someone who's got a switch and is running that Ethernet the last you know street 3rd like over to the next house over the next couple houses often is going to run a local Wi-Fi hotspots so that people who are more transient as users can sort of stop buying connect and and sort of get onto the US that for a little while yeah so something that's there to say about this organization as that has no like 1 real central figure behind the as that it's wrong by the means mainly what users decisions carry a large weight into the community so even though they means have to technical cavalry topologies to keep there were running in to keep everything up to point to some extent the actions of the users really matter we can then that work in there really we have a boys which in everything that's going inside
so let's talk about the hold nailed the room which is how are you gonna below there were real hardware it if you want to so we have replica which used to Cuban knockoff of Craig list there we have a muscle we have the same piece of year so you weekly station M 5 I chose this 1 because it is considered like the top of the line in s that like if you will have 1 of these 2 committees according to where you 1 this 1 sort of fairly good for what we do then that's really what we're sticking with for now so you can see a price in the US right was the sum of the yet so in the US surprise will be something like 81 loss in 63 cents warning Culiacan for 170 lost its doll hold the price in a bit more blood and it's not that but I mean it's still something reachable it's still decent hardware and the same happens for the micro ground relative should we use which are not expensive and in Kuala what like 1 20 or something like that so my involvement of this
I guess began after 2016 we had a 1 0 visit Cuba and then they're became easier for US citizens to go on in late 2016 there was a conference call to become a which is a great conference around serve open source software in Havana that that's the success they run again this year of and and that's where we sort of ran into a over and a bunch of sort of the open source community in in Havana and heard about us now and so I went back a couple times in 2017 along with of an academic colleagues so so Alex Haldeman Iike was and David Robinson uh to uh and uh to train document perspective right like there's this fascinating network out there that we've heard very little about and we we sort of don't have any real technical sense of does this actually exists like we've heard rumors but it but it seems like it's been very quiet it's a it's the thing that we just haven't gotten the attention it deserves a word for word then allowing us to understand what support we can provide back to it so
so how we do this and so from from initial point of contact that we've made at that to becomes we sort of simple sample that much of the people involved to try and talk to them about what this thing actually was and understand it we got to go to a couple different places and see a bunch of the physical you're yeah parts of that what if that is in in the physical world is these Wi-Fi routers and antennas on and we get to connect into it and try and do some some technical sort of analysis of how big is this thing really what's actually running on what is this thing from a technical perspective and and what that looks like this 1st figuring out what are the prefixes what actually is this local network on and then can we understand how many servers are up there what types of servers they are and luckily there there's sort of a partial name system where word depending on how you're connected you may get a DNS order provided to you and you can do DNS name transfers to sort of get the full set of names such services that are there and that gives you start to understand what's going on and then and we did sort of w get calling so just grabbing sort of as much web content as we could out of it to get a sense of you know what are the services what is being was a being used for the and and this this sort of ended up on there's a there's a short paper that was at the Internet Measurement Conference in London at the end of November the or the beginning November that you can look for for a much more sort of like technical details about the of what this network looks like the but in terms of topology this is
sort of like TreeStrap looks like from from that vantage point but you see these red nodes near the center of those of the different pillars that sort of tightly connected and spending half of them using nodes on a lot of times you've got this variable firewall policy were sometimes you the pillar or individual nodes will not themselves again you can't look really back behind them easily so this is a core of you out to the point where that 1st level of netting happens but there's many clients beyond this there's also a lot of Wi-Fi point you're not actually seen that end users but this is sort of the you know the server infrastructure of what sort of an the permanent Service set of services that is running as opposed to the end users which is where you get that much more massive number so to make up the tools to leave something perfectly then where we said 100 thousand users it's use what we think we have because that's the amount of IP addresses we find that so we're assuming a least 1 user of the IP address but it could be significantly it's initially be here for s that right now so here's an example of of
1 of those sort of initial pages that often people end up at it seems it's called the the scope directory services server user moderated a listing of popular services and then on the side what we've got is sort of that coming out of that study characterizing the different services are relative popularity of sort of different things on the network so the started as gaming and gaming is still sort of the most popular set of sites that you're seeing there's a lot of you know that you are well community donor community and downloading that software finding different clans or groups to play with there's also I think of the emergent property that that was exciting to see is that there's now a kind of form activity a lot of sort of active real-time chat that's going on people are using this for severely communication and then you've also got it as a reference things so that a lot of mirrors there's Wikipedia stackexchange are as you move over to the technical side because this is a community that's created its own network you you get a bunch of open source software repository nearest so that you can have your local and Kim Uriah local and local set of Python packages and there's some file-sharing from commerce and commerce that a bunch of stuff I guess this is also looking at the the web part of this network of what we found from talking with investors is a lot of the underlying communication for like how how this thing it's managed but was still not over these forms per say but within teams speak for Java on the upper the or something like that so there's a bunch of other stuff going on here this is 1 in 1 slice of it but you see 3 thousand active what post as well so there there's a significant number of web services that are that are that are part of the cell I also mentioned the thing in the other side that's called that's 1 of the many pages that exist to find when site is active for node within the network
so give you some more screenshots is like at some sense of what's going on here this is what have on the net which is 1 of the the killer home pages so for 1 of the neighbourhoods this is sort of the that pillar has as 1 of its server server intro . you see some common links of the top like they've got their Wikipedia clone our mirror you see the people identify themselves by by something that looks a lot like candles and there there's a very common use of synonyms in on the network as opposed to the real identity so and it's got sort of active things going on in the neighborhood of the answer of what's up with this pillar answer how were doing the
so here's here's what 1 of those mirror sites looks like this one's like a Wikipedia mirror along with with several other share of the slices of things that you can get access to that's just being posted on 1 of these in the there would be safer and stuff that they holding how list with the sum gaming
sites of representing sort of new things you can play is getting out and in 1 of
the sub communities that we found most exciting is that there's this and community called Netlab which is sort of focused on open source software and technology it's centered around a form there is this very active Netlab forum for technical discussion but they run their own get lab instance so they've got sort of a set of community coating that's happening and going on about this uh search engine corolla is a search engine with mn s net of content in that network that they've customizable themselves so it's got its own open-source git repository of you know the code behind the search engine that they've built our for themselves so they also holds like books and or soft people the world from the reverting to more than remark to mimic work for be reused yeah and so that that's really exciting you know 1 of the uh administrators who was involved in this that we talked to was saying it's gotten to a point where there are times when he has questions about like Android phones there been customized for Cuba and this now love form is often more useful in solving those problems than the external internet and so now they're having to think about how we take this content we've got on our network and bring it ask back into the real network as well the
so the rules every community has to abide some rules In the case of s that this is not different because of a myriad of things so the 1st thing you will find if this is from 1 of the pioneers of the the uh when I listed Pilar in this case the rules are fairly it's a fairly common set of food to all of stroll the whole network so it's sort of Eden to attempt a gains the security of the country is Serbian to providing them with services radio TV services and stuff like that which are in accordance with the rules of the country because we had to remember something rules cannot be broken inside any commentary or else you will deal if s that will reduce rules it will not never have gotten the speed so the subset of rules are treated within the community that just at the what's new in you can actually see this something that's community decided which is how what is what do the so it can go from suspending a service to being kicked out permanently from ethnic and this is decided not only by the other name but by a fellow mode uses In this at work the other thing worth saying here is that so there's some collection that is of rules that are based around the long-term sustainability of the network right so the network was to keep existing it doesn't want to have have itself seen as competing with attacks and so you've got rules like don't bridge to the Internet because then you become a top common that some competing with a text and you don't want that on the other of rules and up being a reflection of things that might be solved technically so for instance there is a tension between the gamers who want to be playing games with low latency and the people who want to be doing file transfers which would be used up the network and so some of these rules are things like you can only file transfer in off hours and if we catch you file transferring during peak gaming time you'll be disconnected for a while yep and we might solve that with routers but this also the social pressure also was a very effective way to solve that in in a more easy way so yet we have
here 1 of the most popular forums and this would be like the equivalent to Facebook if I had to begin their work it has that the school we that it's quietly community they do like for the both and stories or whatever you may think so the amount of free seduces this web site if strict 56 thousand this suffer really be among the users at the moment we took these measurements anyway 30 per cent of those users were woman and at that time which was on May the 1st 2017 at 4 PM if I the recall badly there were 5 100 prospective users and this is kind of kind of day for that time because it's made differs from the parade in Nevada so most of the body use tyrants sleeping brolly at that time it did induce the side can be solved in a normal day at the time of the day maybe 15 30 thousand people at any given moment use posting staff and the server crashes all might go the subtractions so yeah so there's a bunch of pain
points here right in terms of how is this network evolving right this is not a walk in the park at 1 of the things that's really noticeable is that this is a community network and infrastructure cost has been a a limiting factor at some that point all the network here we see is under a hundred dollars if you were to buy it in the US right so there's no that limits how much you're going to scale up for you can't have the central point with a really big Cisco router that's gonna like be able to get you know digs of traffic through per 2nd and so you have to uh got the smash and if you're trying to get all the way to the other side you may end up with pretty high latency and the the routing between pillars essential as he has the and so you end up with loops quite a bit but even in the current sort of fairly limited number of of sort of subnetworks that the composite identity is an issue right so we all of this in right time pick it up but there's no e-mail service so when you register you register with you know whatever you wanna e-mail field if it still exists or it doesn't depending on if they've but if what you're using as a site that has sort of taking code from the Internet to set up for if it's been coded and thus doesn't even need verification but this also means that if you forget your password your sort of out of luck uh like this there's not really recovery processes does something beyond finding the administrator of that specific site and saying I forgot my using my password you like said that doesn't always work so so for dates are problem solver self-ordered strontium inside of the network response to 8 years out of date in these columns yeah it's a long time to up date between updates we are hoping to bring some stuff up today but these are mainly sites there were like not really that use just kept on going but anyway that's 1 of the things that 1 of the that's the effect of being away from the from the internet that so for of dates can be tricky sometimes is for some technologies so in the press conflicts and community organization that's a baby point like 2 months ago to of the 2 by the ugly inside our small this small argument and that bring them at work to a standstill in a got to the point where it was to use 1 Pilar holding 2 sides of the work together and people having to rather the traffic to reach stuff in your side so that was a hard time people like eventually got to talk and then for 2 months some people were like if there is going to stop existing today or tomorrow but luckily that did not happen at then people where will to use talk it out and you can have great and this is this is I think there is this whole hopeful of and cautious optimism the network still doing well after on you know the hurricanes that that happened uh over the summer and it's all this last mile problem in the way that the torque on hasn't right there there's all of these Ethernet drops around 3 level that's doing this aggregation around metro area that it has this huge potential and so there's this question of how does this thing keep existing in going forward to playing a role in people's and slides and so what is this regulation look like how does this thing and uprising so I guess I guess we have some
takeaways the tumor is networking and so even as we've got this sort of crazy view of what i official Internet might look like there's much more to the story and again it's something that when you actually live there you you find a way to to get through there's there's a lot of hustle on a lot of like ability to to find out ways to make things work it so what kind of of takeaways sees as it is probably the war slide this isolated community work in for sure is 1 of the 4 biggest match the words right now In particular we did not this that don't use telecom structure please 5 from people create euros for 3rd so please few so yeah I mean as that's this assessment think of I think it can benefit a lot from our knowledge here and I think you know we can learn a lot from how this sort of phenomenon keeps growing because I think what we see a lot of times is that you get this movement of we need more connectivity we need some sort of community network and that then Spurs some sort of larger infrastructural development right 0 sum I ask you will come in or will get some backbone and will connects this community network as it emerges in become seen as valuable to 2 or more traditional connectivity and 1 of the things that's really fascinating in the case of s net is that hasn't happened there hasn't been an official ice-t that's common set well there's clearly demand what's like go in in like solve this in a in a more regulated way and and so that's led to the sort of from new solutions the I guess the final the final point here is sort of moving to the matter like talks at this sort of undeserved community and hearing about this is super valuable and also a lot of work with a lot of people to thank you yeah we have so I like to think some people 1st people from customer occasion Congress you guys really help with every system of state thanks a lot also for and I found the drum roll the the reality gap you guys rock Raven where you are trying to and the big deal do my 1st thing Germany really appreciate that and he was going to have some friends included blowing over there are the biodiesel we use the form in thes so I think the what we see right is like we can champion this sort of thing that these these underserved voices here and it's really great right this is clearly a place that that orders thriving and like his home in a way that that's really exciting and that's really part of the cells are and getting getting him here was there's an IRC channel that's been going on for months where you know the occasional Spidey connection of what the latest problem is and then a bunch of people in Germany and and elsewhere are sort of going in finding the next documentation that we need to to to solve that for the next time several days later when it's Internet again philatelic solve this on and I think that's that's really reflective of the the spirit purity CC in a way that I'm really excited about right that this is sort of this like a personal autonomy that is part of a recessive going in doing things but this this to what model that that we that we can hope for and I encourage everyone to to to do that and like find the people who need to be here and help them get here and because Bill will give back so much more but I think it's also that so few I think it's also the way to to think about how do we build a Congress and then a community where we don't need those champions in the future and people who need to be here and want to be here I can can actually get your more easily so how we lower barriers are to access so 1 1 anecdote of that I think is worth having is so we had a talk at the Internet Measurement Conference and were looking into how do we get someone from Cuba to get to London for this event and there's travel grants but you have to have a full application a few months in advance our and then the the way that the money would happen is you have to know what your costs are months in advance and then it will show up as a check to your institution a couple months later and just is not a thing that really coincides well with this system that you find when you're not in Western Europe and US and so thinking about how these things that may be our our body work within our system right as as someone who's an academic and US I understand this and like the university that I with would find the money for me and then expect to get remunerated but it doesn't scale and so figuring out where these barriers are that we don't notice and how we break them down I think is is 1 of the things that is a continuing struggle that we should have and then I guess that serve on a more serious note I think that that message is 1 that also reflects to some extent on the some of the tensions we've seen a Congress this year I think that you know we we had failures that we should be recognizing the the and and yeah and we need to think about how do we address the how we build some place that is more welcoming of that is that is safe the and and so I guess for me that's the spirit of of how do we come together how we build what we want Congress to be on and think about this in a collaborative way of making the space that is that is good for us and and at the same time is safer victims at a few so before
we look we will need look you made it if you want to ask something new levels or whatever you sold to their home Goals through through through thing of whenever we don't guarantee we will respond to to it at at that look like for instance for the Baltimore have had used the uniform laws and our we have plenty of time for questions so if you'd like to cheer up at the microphones so we can do this all the members of the US this sort concise questions we would like to questions about commons and I'm gonna start microphone number 1 hi thank you find a great attack and 1 can be any legal and political hurdles still has enough for example as I said in highlighted to here than uh uh so I guess if you 1st need to take into account the storms regulations which I'm not that grew we because I think there were recently changed what was that solver I guess shouldn't be a problem but really at the mom just guessing at this point but yeah it should be impossible to do what I recommend you use the shelf you're willing to do something like that because the ball service system but that the rela all it takes a long time the sound then the expression of from out of 100 to these at all but thanks a lot for the great talk on iron curious about what I'm not a novel as so problem and yes that since you run such a huge amount of qualitative clients I would assume that the huge problems for the more is there any security filled with within the network or is it simply not an issue because of the clients are not connected directly to the internet OK so some of all that raise some of all that so 1st talk about encryption in Cuenca regulated by the city law from 2002 which implies you need the permission to use any force cryptography and that's not really applicable because where you into a computer your basic compared to rush to matches and that's so it doesn't really skills of love of global ethnic needs to we comply with it so in creating already here is not really something we can do if we want to keep on going so my work yes there's a lot more work I role so that once they have the people get drunk sorry to but you have always a problem on the basis of horrible stories we have with the few solutions for like wind Microsoft Windows IOS alignments we'd like our best key or of us or like the whole of the whole college of anti-virus there would be you dated weekly that usually comes in a pocket they would get their biases people don't like to data on the wire so they don't really know how to name that sucks I mean I guess that the the saving grace for is you're you're offline and so what is it now where is going to do a context filtrate your data it can show you ads so a lot of times this ends up being fairly harmless so we can corrupt the hard right and that sort of thing you half of the Atlantic of the saying I don't know if you guys know about that a lot of times that it is not a quite as severe just because it is an environment that the malware also is not expecting to find itself yeah thanks for this answer we have some more questions and there are also some of of from the internet from our own US industry these signaling to give me a question thank you from a couple of brief questions around ESnet what both as like before the embargo got left at it set this city that's and not connected to each other if you discussed possible solutions to connect them families in angst how many you just look that to take and how much would that cost through I get from going
back to these for a 1st so we mean
a set take great so let's take into account the map of Cuba so that part of the always have an ACC fairly flat it's you know fairly easy but once you move to bring the real that place fast mountains be Piedmont things and it's quite complex to rout stuff through the but in the case of sinful some provides industry using may be easier if the SER radio is some S serious stuff for dumb and that there's something that people are being considering but having gone through the yet quite well in India but there is a cultural B S the are for these long often a blink if you have any for the murder uh 0 before the embodied look pretty much the same I mean they model hasn't been lifted the US tried to re-establish relating to made back it up in the would that be as it was pretty much the same nothing really changes it it's crime the controlling the mean but it's been growing since 2008 so there's no real Miller real difference things as great as another number 3 please and what are these others and and the services found themselves this is someone going around like and or just going out of ideology and the 2nd 1 and you see the Internet slowly coming to Cuba and you think it will eventually replace it because of better connectivity and service OK so that is the example of moderate another rules not a formal 1 1 question that actually want to answer his 1st with another 1 of the for the upper hand so I will answer your 1st question they will come talk about later if you want so how does this that finances itself so people usually give wants to see a moment to remote include apply school I mean that those groups of which of these 2 paragraphs In order to have morning case some equipment gets most of the Lord breaks or or whatever happens we ordinal wants to upgrade the gear task is received once you see amount which is not that much compared with like want to see our for so that's kind of the way as that finds himself it's basically if this doesn't happens everywhere in some places the prices my vary or in some more places they're still all because that it's applied are in there like C and all of our really strong structure already so that time Mayberry we saw a lot of scraping together so for instance Netlab had a crowdfunding thing for an additional just for themselves where they found users throughout of their services to help improve that are Duke imagine that the sort of in kind and scraping together but it is sort of ground up community funding since the lot update microphone number 100 member 1 question some of those things and I am a man to the BBS is 190 is under connections to the some hideous something that's all I rather BBS for a while them from the truth that sticks is if you but I mean it's similar to that in the sense that you are basically sometimes trying to find a proper around to get to the page you want because died might have changeable or nite and forward it's not working and stuff are breaking down and people are coming in 4 in the morning trying to figure out where the kind of acts as a service but this basically it's kind of like the BBS in memory this kind of yeah OK cool thanks for the answer a microphone number 4 so policy and um different uh cities communicate to each other so this is not there OK it's on the same page so right now I said the community of all right now lord of the series of parking rejoinder on ethnic does not something we are being able to recall so there is some victories of other models of which is the nearest Berlin's you'll find it's like 200 kilometers and get to see a Wi-Fi hotspot a Wi-Fi router 200 kilometres if you 1 please let me know if the random alone try to buy it but the answer is these are each their own organic community that totally separate our they don't necessarily even have the same brand at the door branding it's just there are these land networks that existed at least as many cities yeah OK well not a phone number of treaties the thank you would have this this and that is it's a building some kind of pressure on the actual telephone telephone company and minimal and then becomes cheaper or whatever not really I mean we try to keep away from it takes like we used knowledge like we'll try to get to the internet we don't try to we try to parlay with them when they're they what they want to parlay we'd also but for the mean time we used the mind then we use keep fumbling thing which is trying to get people this different surveys and trying to get people's a place to gain chart and whatever people is people the limits yes OK and we have 1 more question from the internet dear signal
Rangel please give us there's 1 question yes thank you a lot about satellite Internet and telephone lines to connect the city's case so the 1st to really hot spots from going to yeah and so I think I think again you're now at the point of a quite bit of cost right where both what is the motivation to to connect these 2 city networks because that sounds like a hiking especially satellites you're not doing your landing anymore but of satellites do new special license to have sort dishes and Q what is that quite hard to get and and the constant phone connection is either going to be pretty low bandwidth or a is going to be pretty expensive and again why why are you doing that cost of by doing it the other thing you're doing is you're exposing yourself to much of risk that that the purpose of this cross country links that a real time is often going to be much more about commerce and sorts of things that a Texas going to feel like a eating into its business but potentially you in more trouble as opposed to the community nature which is often inherently local also for it were a these running on the infrastructure that's formed by 2 companies it's quite dangerous because at the moment they decide to go 1 euro blink Tutsis anymore they would use several and you will be stranded so it's not our gradient can ever use telecom infrastructure so bomb this that was clear OK thank you guys have someone might have 1 6 I'm not sure whether a tendency of through yes please direct the question they keep uh I'm wondering if there's a really low latency in interconnection uh call sneaker net between the networks and with the outside world for instance to share a file storage states to the six-year-old software yes I mean and and this is also what OPEC hectáreas yet freight by this with the way if you look at what is this Wikipedia mirror this is someone you went to their institutional connection or had a friend who was traveling internationally get a lot you know StackOverflow dumper Wikipedia dump in and then connected to a computer the tiniest net and now you've got a mirror that people internally can use but so it's a lot of how these resources and up there is through the speaker that mechanisms OK we have not much time left the microphone number 1 please make a short question so why is the official Internet so crappy and inexpensive a political reasons or attentional reasons or his might have the actual Austin or just a furniture question but I can give you 2 which assurances the first one is that except to quite a lot of to have access to the internet to any underwater fiber cable died lost what I was thinking was 2012 for a good connected movements well I might be wrong around the year 2012 2011 maybe where on the page and they at the correction from the cable segments and tell the core was so they had to roll to all whole freaking country which may not be as because your money but that happened in the past 5 years I the they're struggling with that because it's quite the method for developing countries and that's 1 of the reasons dealer reason is because they truly believe I think this is something I think I think it makes us things they Wi-Fi solution like this whole hold your way around and that's not the solution that's there going to be a solution space to schedule 1 high Latin something which is something you definitely don't want for whatever you're doing a line so it's kind of a hard question to answer because I don't really have enough data to give you a proper response thanks was that the 1 part or both parts of your answer that's my answer you have the 2nd to the things you know the following we we might have left some time for a generic question that it gets the short answer is there anyone at the microphones that has such a thing prepared no 1 in our model 1 6 so cheminformatics discovered the mentioned that uh you have forums on the excess dissenting opinions here there were hardly immediately moderated out all I don't the forms that much I mean the form they usually vis-à-vis the developer forums and people there usually stay up political for whatever reason but I'm not sure actually I think at some point it might be edited out if someone brings these 2 an admin but I don't think it's like automatic something that happens site in the the 2nd thing you may get so take some time to for the admins to remove that kind of content here there is a lot for this amazing to organs of insights in order to to to thank you Dave

Fachgebiet Informatik
Abstract Internet access in Cuba is notoriously restrictive. ETECSA, the government-run teleco, offers 60 wireless hotspots in parks and hotels, allowing foreigners and citizens alike to "visit" the Internet for only 1/hour… That’s what most tourists know about the Internet in Cuba, but of course, that can't be the whole story! In this talk, we'll take a deeper look at what life is like for Cuban hackers, and we’ll get to tour a vibrant set of community-driven networks that typical tourists never see. The story that emerges is an inspiring view of what communities can (and can’t) accomplish in the face of adversity.
