Sorry, I can't tell if you're being facetious. The article implies that the cubans are, for some reason, receiving packets over fiber, but sending over satellite, which, for all intents and purposes, is insane. It is a real mystery as to why anyone would configure a network to operate in this manner. It is akin to having a 10gigabit fiber line in your office and choosing to have all outbound traffic routed over a 1.5megabit DSL line instead. Madness!

The Internet in Cuba is characterized by a low number of connections, limited bandwidth, censorship, and high cost. http://en.wikipedia.org/wiki/Internet_in_Cuba http://en.wikipedia.org/wiki/Internet_in_Cuba Madness is exactly the word the Castros were aiming for.

Yes, that configuration is madness, but it's no mystery. The mystery is why is that configuration in use? The answer probably has to do with reducing internet usage in Cuba to prevent a Cuban Spring. And that really isn't about the cable either.

  The most likely explanation is that traffic is bi-directional on the fiber line, but a lot of additional latency is introduced by software based (as opposed to hardware accelerated) deep packet inspection.

It's more like having a 10gigabit fiber line and choosing to have outbound traffic routed via carrier pigeon. It's latency, not bandwidth, that makes a satellite connection maddening.

  also, cost. Sending to a satellite is much more involved than receiving from it.

    Not once you get to the size of circuit here, and in general, receiving from satellite is far cheaper than sending to it.

Because its a corrupt and incompetent regime that relies on censorship? Maybe all their filtering toys currently only work with the sat uplinks. Who knows. Non-free countries have crazy networking to remain non-free. wikipedia: Cuba has an Internet penetration of 1 to 3 percent; making it the lowest rate in Latin America and one of the lowest in the world /this is a feature not a bug.
