I suggest you join the outages listserv (outages@xxxxxxxxxxx, https://puck.nether.net/mailman/listinfo/outages) for those kinds of questions. There was an ATT related issue Wednesday, but nothing noted there for Thursday.

Subject: [Wireshark-users] AT&T backbone issues 08/04/2011 1230pm - 5pm CDT?
Did anyone else notice any problems on the ATT backbone yesterday? We had one VPN tunnel go down (out of 8) and found the problem was within the ATT internet infrastructure. After being transferred around ATT for about 2 hours, the problem seemed to resolve itself.
We are in Baton Rouge. LA and our VPN connect from here to Connecticut. We found that packets from Connecticut were reaching us here, but were not gettting back to Connecticut. Our tracert failed at 12.81.24.97. After the problem resolved itself, we were able to continue on to 74.175.192.22.
I am curious if anyone else had similar problems yesterday. Also, does anyone know a decent web site that shows (in real time) outages and delays on the internet backbone? I found one - http://www.internetpulse.net/ that was interesting. And what about a map showing where these IPs physically reside (as opposed to where they are registered)?
The site rocks, Stretch! Keep up the good work.
