I'm sorry, I'm sure that this is going to the wrong person, but there didn't
seem to be an appropriate category for this bug...
I noticed that in the mirrors list provided by visiting
<http://mirrors.fedoraproject.org/mirrorlist?repo=rawhide&arch=i386> you will
see that the first and last mirrors are http://download.fedoraproject.org and
http://Download.fedoraproject.org. These are of course the same, and if yum
fails on one it's not much good switching to the other. Please forward this bug
to whoever is responsible for maintaining the mirror list.
We're working on the list, it will be fixed soon.
