Comcast Late Night Lurkers? (Chicago Problems)

Any Comcast engineers lurking on here?

Have noticed a significant issue with endpoint connectivity into our private clouds starting around 19:30 central, continuing on to now. Have also seen some issues with devices accessing via our customers’ WAN connections through AT&T, suspecting some sort of transit fun. Tried reporting via SMB Coax and residential— not even sure why I tried. Normally, this amount of flap is not an issue for us but it’s causing some abnormal adverse effects which is an issue for us. :blush:

We’re seeing this on customers’ networks that we know are on SMB HFC, ENS, Metro-E, pretty good spread. As well as some sprinkling of AT&T/ICN (Illinois Century Network). I am hoping it is a bad peer that can be told to stop or routed-out.

Any help or investigating would be appreciated.
