that the internet broke pretty good yesterday.  Apparently someone added some new routes, and it broke the 500,000 route limit in most BGP routers.
Oops.
But this has been a long time coming, even back in 2003 when I had a full BGP load I was running on a 7206vxr with 512MB of ram.
So if you had connectivity problems, that is what was going on.
Fun times for sure!
Oh well next time you could fix it yourself:
