This is probably:

https://bugzilla.redhat.com/484491

There is a problem with pythons URLGrabber module where it can't access 
https content through an HTTP proxy.  In F11 the mirrorlist addresses 
are HTTPS whereas in F10 they were HTTP.

The quick fix is to go into /etc/yum.repos.d and change all of the https 
URLs in the .repo files to HTTP.  That worked on all of our systems.
