The UUNET status web site was last updated on Fri Mar 30 20:20:14 EST 2001
and indicates no problems on the network.
The Matrix (average.miq.net) shows several drop-outs in network performance.
Numerous other providers and customers sent me mail that there is a
routing issue with UUNET. No word out of UUNET though.
I was working with UUNet on our issue, and they said that the NOC and TAC
departments are looking at the issue. What they did not say is how large
the issue is. Took us an hour to convince them that nothing getting past
their side of the WAN link was indeed a problem, but that's another
story. Those were the symptoms that we were seeing, absolutely nothing
past our side of the WAN. Others may be seeing other symptoms. For
SAVVIS customers in NY, the BGP session with UUNet is admin down pending
resolution, so if you have the SAVVIS pipe admin down because of this,
fairly safe to bring it back up now.....

I just spoke with SAVVIS (spelled correctly per marketing 
and they were very informative and helpful. They explained that they have been working with UUNet, but have not seen any resolution yet. I turned up our link and BGP session again and all traffic destined for AS701 went through Sprint, but it still didn't get past the Sprint-UUNet peering connection. Something is screwed up with their ingress filtering from their peering connections. All traffic to UUNet is working fine and everything on their network is reachable via our UUNet link. UUNet is broken from any other AS I can find.

Just got off the phone with UUNet again - this WAS a leftover from their
routing problem earlier today, and according to them, it was fixed as of
3:24am EDT. I tried to static route www.uu.net down our UUNet pipe, but
that didn't work for some inexpliciable reason, so I just took a leap of
faith and trusted them. I turned up the BGP session again, and all seemed
to work well, I'm seeing input and output across the
interface. Apparently some routing process got hung and had to be
restarted, the person on the other end of the phone was a little unclear
as to what the problem really was.....
