Drop unreliable mirrors. It happens often enough that they should be 

Update lists mirrors; it seems that Yum downloads a fresh list each time 
(yuck, I'd rather see the list in an rpm that's updated as needed), so 
that should be a quick fix. Once a mirror fixes its problems, relist it.

I've not noticed that Yum can be configured to do that. I can make it 
update but not download, but I don't think it can download and not update.

up2date can do that, and that's what I did with Taroon beta.
