We had reports that your mirror (ftp.uninett.no) is no longer up to date. Usually this would not be a problem as MirrorManager is disabling outdated mirrors, but as you are also using report_mirror which claims that your mirror is up to date, the state of the mirror is flipping.
From looking at http://ftp.uninett.no/linux/epel/7/x86_64/repodata/ it looks like your mirror stopped updating around April 9th for EPEL and Feb 28th for Fedora: http://ftp.uninett.no/linux/fedora/development/rawhide/Everything/x86_64/os/...
I've disabled the site now, but I can reenable it when you get it fixed up, or you can do so at https://admin.fedoraproject.org/mirrormanager
Thanks for mirroring and looking into the issue!
