[outages] US West Coast Massive Tier 1 Backbone Issues

[Cary Wiedemann]

Hey All,

There's a few threads on this already, but they all call out specific ISPs
when this trouble isn't limited to any one last-mile provider.  Nearly all
tier 1 transit providers are experiencing loss on the US West Coast today.
Some examples:

Comcast/Level3 peering point in Seattle:

Telia/AT&T in Seattle:

Hurricane Electric/Cox in San Jose:

And this isn't the half of it.  Very few tier 1 transit providers are
unaffected.

So much for carrier redundancy!
