L3 Issues

Mon Aug 1 17:47:42 UTC 2011

We were seeing issues here as well, we have BGP to Level 3 down until they
stabilize.  We were seeing a number of sites as unreachable, but ping tests
from the Level3 IP address on that interface were working.  Looks like
perhaps they stopped advertising our addresses or were advertising them
through an incorrect path.

Seeing a big drop in outbound traffic on our L3 link starting about that
time (we're a web host).  Getting calls about sites down too; all the traces
I've walked customers through so far have died on L3 networks.
