AT&T/Alternet outage in Chicago?

We were noticing some routing problems between AT&T (our provider) and
alternet/uunet sites. This seems better now, but AT&T still has a master
ticket open. Anyone seeing similar things, or have more information?

I'm somewhat concerned too... they seem to have lost the route to the
C-Class nof my legacy Toronto-wide for several hours today, and if it's
going to happen again anytime soon i might need to step up my migration

I'm not sure what happened, and all my normal sources came
up empty. I did look at some very old monitoring pages, and
Downers Grove suddenly showed up in some traceroutes. I hadn't
seen Downers Grove in years.

It was almost like some forwarding tables were corrupted in a
couple of routers in Chicago. But there didn't seem to be a
pattern I could determine before it cleared up.

I've been seeing lots of strange problems with my AT&T SDSL for the last couple days. I think it has to do with AT&T's integration of their cablemodem services... because it started in the bay area the same time they started bring their broadband cablemodems back up. The routing is also different than normal, and the Flowpoint router is getting lots of errors and discards. (I'm dumb about SDSL, all I know is that these numbers increase whenever my connection slows to a crawl).

The error count on the router is also way up:
