Broken EPEL mirror?

We are using mock to build RPMs for CentOS 7. The mock configuration for CentOS 7 is set to use this mirror list: http://mirrors.fedoraproject.org/mirrorlist?repo=epel-7&arch=x86_64. From this mirror list http://ftp.uninett.no/linux/epel/7/x86_64/ seems to be the preferred mirror and is the one which is always chosen. This mirror seems to be broken however. There is partial repository metadata and no RPMs. This is very annoying because it also breaks the other mirrors since the metadata is available and causes Yum to store incorrect relative path to the RPMs in the other mirrors. Can this mirror be removed from the mirror list until it is fixed? Because right now all our CentOS 7 builds are failing because of it.
