The great firehole of Nicaragua

2009.06.15

Ufff…

I have spent a couple of hours connected from Norman García’s house, in Managua. Norman is most kindly hosting me at home for a couple of days before we leave (tomorrow) for Estelí, where the Central American Free Software Encounter will be held.

Now, the network feels really slow. However, it can sustain download rates of around 512Kbps, quite acceptable. Latency is what kills. But… I was stunned with mtr’s results to my home server: Host Loss% Snt Last Avg Best Wrst StDev

Please, somebody explain the basics of routing to Claro/Enitel. This just does not make any sense.

Looks like they might have a

Looks like they might have a mesh network for their backbone.

Very handy

mtr has been my favorite tool since I met it, diagnosing our poor networking at DC6. I think the game you refer to was “Pipe dreams”, right? Well, here from Estelí the network is still slowish and with huge lag, but at least it is not that insane anymore.

yeah lol

i lived there for several years. the traceroutes were always dismal. it makes things like online gaming and p2p pretty much unusable :(

So there’s a conference in Esteli? That’s amazing. I guess linux and free software have gained popularity since i’ve left.

mtr

I didn’t know about mtr… I just installed mtr-tiny and is pretty handy to say the least… I just wish that they don’t had the same routing problem with water or electricity.

This routing just made me remember an old game “plumber’s nightmare” I think was called…

But if you remember until recent time, to connect from telmex to alestra or any other major ISP on MX, you had to go to LA, Dallas or even Atlanta and return! Granted less latency, but more or less the same number of hops.
