[Yum] Broken lookups?

[peter]

Here's a classic example of what I was talking about.

I just ran yum --disablerepo=dag -y update on one of my servers.
It the repomd.xml was not available for 
http://mirror.atrpms.net/newrpms/apt/redhat/en/i386/fc4/repodata/repomd.xml
but I just copied and pasted the URI into a browser and it *is* there.

I'm running yum on all my other servers (all same version, all
under FC4) and they didn't come up with this message.

Once they've finished I'll type yum again and see what happens.
