Just happened again, and we've been seeing crazy packet loss through slc on a L3 route from Kansas City to San Francisco as well. Something has been broken in SLC since at least 8:50 AM Central.

Yes, having a lot of packet loss to a Salt Lake City HSIP circuit I have with them.. No problem with my Denver HSIP circuit though. I have a ticket open with them and the tech was not aware of an outage.

Had some alarms go off this morning regarding an apparent problem with Level3 transiting Denver. Anyone else see anything? Level 3 seems to be unaware, still, at least according to their support desk.
