What I saw was a lot of unreachable nexthops (I'm in LA2) on routes 
advertised through the route servers. Most of my direct BGP sessions 
were down, but a handful were still working including the route servers.

For example, I was getting routes for AS29791 from the route servers, 
but nexthop 206.72.211.106 was dead to me. Not to pick on Internap other 
than a mutual customer called me directly at 1am and wanted to know why 
things were down.

I killed the route server sessions and went back to sleep.

Feels like LA1 and LA2 got split, but however the route servers 
interconnect still worked, which was problematic.
