Hmm, yeah, you're right.
The idea was to get the closest 25 servers and then test their
performance from there...
I haven't gotten too deep into routing protocols, but I'd bet it
wouldn't be too hard to have zebra or something like that dump it's
bgp table into a sql server, and do lookups from that... Is anyone
already doing something like that already?
