Hi all, 

Anyone have any information on the 20 minute (or so) flap that appears
to have occured in Washington between AT&T and the rest of the world?

We saw a complete outage of connectivity to several APIs at a few
parnters who happen to all be behind AT&T.  Although in BGP the routes
were still being advertised across this peering from AT&T to the world,
traffic just died at the washington peering with AT&T irrespective of
which path we took.  (3 different transits here).

Just curious.
