I had real problems with yum {similar to what Tim saw} when I had 
fastest mirror enabled. Try turning it off. In fact I got the drift that 
fastest mirror intends to cycle through every mirror, downloading that 
1.~ MB file, and timing each one. In that amount of time/downloads, I 
could have completed the whole update with a fifth of the downloads.

The other good thing to check is to point your favourite web browser 
directly at one of the mirrors in the list. Check the date/time of the 
repo files. I think they should be near matching.

Also, on a mirror I know about they mention that they rsync each 8 
hours. Now if their rsync schedule is ahead of the fedora build push 
time by half an hour, their mirror wont get updates until 7.5 hours 
later. In the meantime, if repomd.xml is read from the main fedora site, 
it may be indicating that filelist should have a particular checksum, 
which isn't what is currently in most mirrors. Large Fedora updates may 
also play a role - eg openoffice, might slow the speed of getting the 
mirrors in sync.

In fact, since I would rather not use international links when files I 
need are in my country I have used a newer yum conf item as shown: (.au)
/etc/yum.repos.d/fedora-updates.repo
...
baseurl=ftp://mirror.pacific.net.au/linux/fedora/linux/core/updates/$releasever/$basearch/ 
 
ftp://mirror.aarnet.edu.au/pub/fedora/linux/updates/$releasever/$basearch/
ftp://ftp.planetmirror.com/pub/fedora/linux/updates/$releasever/$basearch/
mirrorlist=http://fedora.redhat.com/download/mirrors/updates-released-fc$releasever
failovermethod=priority
...

- I read the mirrorlist, found my in country mirrors, and made these the 
baseurl's.
- priority means try them in listed order.  (otherwise it is random)
- mirrorlist still active in case my fav three aren't up to date yet.
