Ok, To follow up on the script output.

mirror-out.txt: http://fpaste.org/238633/57898001/

I guess it needs to be run when yum is not working with any of the mirrors... EPEL 7 seems fine today while doing a fresh install.

If I notice a problem again I will try running this script and letting you guys know and the output.
