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

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