Yum network problems for Dag's site?

[STYMA, ROBERT E (ROBERT)]

I've been off on vacation for a few weeks and had
the mailing list turned off during that time.
I ran yum update upon return and everything worked OK.
Ran it again last night and again this morning and
had errors from Dag's site.

As can be seen in the log below, the file has zero size.
Has anyone else seen this?
Is this a site problem or just my machine?
