If yum were to retry using the alternate IP addresses, this wouldn't
be an issue. Windows Internet Explorer manages this trick nicely, so it
can't be that difficult...

If you have more than one machine behind a proxy, they will randomly
pick servers from the mirrorlist and use different URL's, so you
not only don't save the bandwidth by re-using the cached copy, you
duplicate the copies in the cache. (Fedora already does it that
way).

Now run a bunch of machine updates through the same squid proxy
and see what happens. How about fixing yum to understand what
multiple A records in DNS is all about?
