You've hit a very large part of the problem square on the head there 
William.  Because there are mirrors here and there, it seems that a 
truely inclusive mirror list, including the actual location of the 
machine one might be accessing so one can actually make an 
intelligent choice as to where to point yum at, is a very elusive, 
almost a state secret, thing to find.  Ask on the list here, and get 
pointed at the downloads.fedora.redhat machine, a machine thats never 
served a package up via yum or up2date in chunks bigger than 10k per 
fitfull 1 or 2 minute intervals.  Watching paint dry is more 
entertaining.

The way it is, one tends to hunt around thru what may be a 30 day old 
list you've grabbed out of the FAQ or some similar location, pick a 
site thats got your stuff and can feed you at 50k+/second, edit it 
into your yum.conf, and the site disappears 4 days later as has been 
the occasion twice now for out of the states FC2 compatible sites for 
me.

I've got one box stock FC2 machine that hasn't been updated since the 
Ooo.i8n package was put up,  yum has pulled it probably 25 times now 
in 3 different day long invocations without getting a good md5sum on 
the 6 or 7 occasions it managed to get the whole file without puking 
over a bad header checksum and starting over from byte one.  At 3 
hours or more per attempt I finally put it into the exclude= line, 
and I hope the next time I try, it doesn't die from dependency hell.  
I'm getting the impression that this file is scrambled well before it 
hits the cat5 cable on the back of the server in Research Triangle 
Park, which is where I believe that particular yum.conf is pointed.

I love to find a server in Pittsburg, it would be 600+ miles of copper 
and glass closer to me than the fedora boxes.

Yes, finding a good server sure is a huge secret.  Fixing that sure 
would go a long ways toward making yum a pleasure to use.
