It's resolved now, but we had customers calling in saying they could no longer get to their sites.  The traceroutes to us were dying at the servers, and a reverse trace to their public IP address was showing the trace dying a few hops past our borders.

What kind of issues? I just checked two 10G connections from 350 Canal 
and 1905 Lunt and don't seen anything of concern. Most of my traffic 
stays on Level3, so I only briefly checked that I could route off Level3 
from the connections. Seems fine here
