>Yes, it appears Qwest was leaking routes, but they are fixing it...

Its always so much fun to watch billion dollar companies dance around
the issues.

Qwest's spokesperson could not confirm nor deny any problem, and
even if such a problem existed considered it a confidential matter.

On the other hand, C&W received top billing on the news story, probally
because they were one of the few providers to actually give any information
to the public and reporters.  Grrr.  I'm not a big fan of C&W, what
are your peering requirements this week?; but I don't like to see
providers getting zinged for being open about network issues.

However the root cause is a very old issue.  It takes two to create
a route leak.  One to announce the erroronous route, and one to listen
to the erronous route.  The proper router filters on either side of
the connection would mitigate the problem.  Everyone knows the basic
issues.  1) cisco routers can't hold the extremely large access-lists
required to fully filter peer-to-peer connections between large providers.
2) some providers don't make available the information needed to
accurately verify their routing information.  3) review the archives.
