I think this is pretty simple. Its just that the closest city to you where
ATT and XO peer is Chicago. If they peered in Dallas, it would a whole lot
better.
I get this all the time, not as bad as this, going to sites across town (LA)
when a trace regularly goes via San Jose and back.
I guess the Internet isnt as inter-networked as it could be, and less and
less so seemingly.
The old idea of mutual peering being good for the net etc seems firmly dead
nowadays.
