[outages] AT&T SF Fiber - Major Packet Loss

[Mike McLaughlin]

ATT in Northern CA is having another widespread packet dropping event. This time it seems some of their (internal) routes are flapping into and out of the state. Started around 20 minutes ago (this time Dec 18, ~6:30PM PST). Same routers having issues.

I've been seeing 30-40% packet loss just inside AT&T's network (after an NTT and Telia handoffs) in San Francisco starting around 5:13PM PST. Specifically, it starts dropping at sffca21crs.ip.att.net (12.122.114.30<http://12.122.114.30>).

ATT Fiber DIA customer. Where the loss starts I'd guess it's a large region impacted.
