Cool. I downloaded that 4.3 MB file.   I suspect we could peer with
Panama. I believe like Colombia, they are also quite advanced with
regard to telecommunications, and it's close. The city I live in
(Cali) is actually much closer to Miami, Florida than Los Angeles,
California is.  And maybe we could peer with Peru, but that's a long way
to our South.


Afaik it is impossible to deduce from the URL if one node is located
nearby or far away.
Eventhough as i live in europe, i can register and use a japanese URL.

Secondly, i fond out that ISP do funny tricks with routing: My
connection to my next-door-neighbour goes via a transcient node in
New-York (high latency).

Only traceroute can give you a clue if a node is local or not.
And even then there is a question of available bandwith....
