>I'm from Cuba and I can say that weekly package (el paquete) always contains files from previous weeks, so what's real new each week is up to 200 GB
Right, thanks! I made the erroneous assumption that the bulk of the data changed weekly (thanks to that "... 851GB ... at 11Mbps 24 hours a day" thing). Keeping the AV updates/some text-heavy-craigslist-alike current is an entirely different proposition.
Here I thought this was a revolutionary high-throughput sneakernet content accretion system possibly operating under the government/telcos collective nose, but as others point out it's probably more like the warez FTPs of the 90s. Here's hoping wider pipes, both technologically and ideologically, come to Cuba soon.
