Re: [outages] Fiber cut in northeast Minnesota on Tuesday, August 3

I'm not sure if this is related or not, but I was definitely seeing loss from SFO <-> STL over St. Louis this morning (~8am - 11am PDT), and various folks were reporting issues with Level3. I've seen similar Level3 failures in the past, and they all seem to exhibit the same behavior: - Traffic to x.x.x.1 is fine - Traffic to x.x.x.2 is fine - Traffic to x.x.x.3 shows 100% loss - Traffic to x.x.x.4 is fine It's as if there's a link aggregation that's hashing by IP, and one one of the links stops forwarding, but doesn't go down. Just a wild guess.
