Hey, I've been using AT&T's network for a while now, and I have a lot of very
poor performance issues like this for a long time. The easy answer would be
to trash AT&T but we've got a contract with them that hasn't expired yet.
Since these are network related issues, I'm wondering if anyone on NANOG has
a clue as to what is going on/the best people to approach. I've been calling
folks at AT&T for several months to get answers that amount to "we are
upgrading this link to an OC3" and even after the upgrade, the performace
still sucks.
