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 (67.36.65.16). Pinging 67.36.65.16 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 67.36.65.16 (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 ? ---Mike -------------------------------------------------------------------- Mike Tancsa, tel +1 519 651 3400 Sentex Communications, mike@sentex.net Providing Internet since 1994 www.sentex.net Cambridge, Ontario Canada www.sentex.net/mike _______________________________________________ NANOG mailing list NANOG@nanog.org http://mailman.nanog.org/mailman/listinfo/nanog
