ATT Broadband / RoadRunner Routing Failures

Wed Jan 24 17:04:35 UTC 2001

The ATT Broadband / MediaOne RoadRunner network in New England appears
to have major routing problems. Their recorded announcement indicates
they're having connectivity problems resulting in people not being able
to reach web pages. Of course the problem covers more than the web...

Traces to IP addresses of places I need to reach fail within the ATT
Broadband network, or within the ATT.NET space (i.e. either in net 24 or
net 12). This has been going on since at least 6:30AM EST.

I first noticed an inability to reach quite a few DNS servers. I can get
to my colo, though. My servers in the colo appear able to see everywhere
(so hopefully the reverse is also true). Looks like some very broken
routing going on in ATT land.
