Comcast/Cogent Peering issue at 56 Marietta

Anyone else seeing packet loss starting at the peering point for Comcast and Cogent at 56 Marietta Ga? Had someone mention it on IRC about seeing issues from Comcast customers. I ran a few MTR's to some of our customers and found one site in the Atlanta area that I could reproduce the issue. Others in the metro area were fine if they bypassed that data center/peers. like xo to Comcast was fine. On this location I don't have an actual device to do a reverse path on.

Yes, it's congested, and (judging from duration, and public statements from both sides) unlikely to get upgraded... On Sun, Jul 21, 2013 at 4:37 AM, Mitch <mitpatterson@gmail.com> wrote:
