[outages] Level 3 <-> ATT

[Bill Wichers]

Looks to me like this might be an issue with Level(3)/ATT peering in Chicago.

I do have one customer complaint of intermittent connectivity which might be related to this issue, but I don't have an IP from them to test yet.

We connect into Level(3) in detroit too. Want me to run any traceroutes from my side to help you isolate anything?

We haven't received any complaints, but we have two other carriers so we might just not be seeing the problem.
