From what I heard, they lost an OC3 from Los Angeles to San Francisco.
They apparently are running at such a capacity that when they lose an
OC3 their entire west coast network blows up. 
We lost a DS3 IP feed to them in LA for about 8 hours yesterday. Even
once connectivity was back up, BGP sessions wouldn't come back to
life...
Getting ahold of a NOC or IP tech was impossible.
