It's not their fault (not counting poor decisions of where to peer or buy
transit), it's INAPs.

Speakeasy uses InterNAP for transit... Though why a DSL provider would
pick a company who's model for optimizing traffic is far more useful
outbound then inbound is beyond me. Maybe INAP gave them some $200/meg
transit to try and stay in business...

And InterNAP uses QWest for transit...

Semi reasonable on qwest's part... Can't afford to peer with everyone
everywhere can you... :P

Well you did find some broken DNS at AboveNet... (or else they're trying
out some new IP over teleportation technology)... From tracerouting around
a little bit it looks like that hop 13 is actually an OC48 between core1
and core4 in sjc2.above.net.

Over to another facility in San Jose...

Well who's to say that InterNAP didn't find a better path... It's always
possible that using Qwest and peering with AboveNet in LA is better then
using Sprint and peering with AboveNet in the bay area...

That being said, it's more likely then not just minus points for the
ASimilator... Can't win 'em all...
