Step 2 is the hard part.

Amusing Traceroutes From Argentina

| Comments

This is traceroute output from a server in a datacenter in Fremont, California to the IP address of the DSL connection in the apartment I’m staying in in Buenos Aires:

Hop 5 is the interesting one. (That lands in Buenos Aires, by the name; packets after that aren’t getting a response.) So Global Crossing is routing this over a satellite connection with ~200ms of latency?

The same trace in the other direction, from Buenos Aires to Fremont:

That’s a little better; the long hop is over seabone.net, “the international backbone of Telecom Italia”; hopefully a higher-capacity land link but still slow.

No wonder net access from Argentina to US sites has seemed uniformly slow.
