I'm at a client site who is multi-homed to Verio and C&W.  With both links
up, various networks in C&W's net are unreachable with the same
configuration that yesterday worked perfectly.  The only massaging of BGP
announcements their doing is with recieved routes and nothing on what
they're sending out.  We've taken the fractional DS3 to C&W down and
everything is working again.  Maybe this would explain why it just quit
working for some reason.
