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. jm

i sit behind cox-cable service at home, and in troubleshooting why my connectivity is *so* horrible, i find the following traceroute. does anyone do any sane routing anymore? does diameter matter (we used to talk about it a long, long while ago). i guess i'm just old and crusty but this seems to violate so many natural laws.
i find in more random testing that i seem to be a minimum of 15 hops from anything, and it's not just the # of hops, it's the *paths* i travel. bouncing between two cities several times, on several different provider networks, from one border to the other.
wow.
