Subject: [NANOG] AS7132 issues in Chicago to Cogent and Teleglobe ?

One of my customers (out of AS11647) is seeing a lot of packet loss to their
office in SBC's network (AS7132). The site is behind one of SBC's BASes
(  Pinging when the path is through Cogent and
Teleglobe is showing periodic packet loss. It will be clean, and then all of
a sudden I cant ping (and anything past it) for about 15 seconds
and then its clean again....  Both my Teleglobe and Cogent paths meet
SBC/ATT in Chicago, so I wonder if there is a common fault there or near
there ?  My customer's US operations tried opening a ticket but was not able
to get any info to SBC/ATT past first level support.

Anyone know of any issues ?
