We had reports that the Fedora mirror mirror.umd.edu is hanging for some users. I can also see that the last rsync scan of your Fedora mirror took over 6 hours. Somethings seem to hang or are very slow.
I disabled your Fedora mirror for now. Once you had a chance to look if there are any problems you can re-enabled your mirror in MirrorManager again or let me know, I can also re-enable it again.
Thanks for supporting Fedora.
