There has been a report that your Fedora mirror 'mirror.as24220.net' is
not totally up to date.
I had a look at your mirrormanager entry and I see that the crawler also has
trouble scanning your mirror in under three hours.
This is related to the fact that your rsync server is not reachable
$ rsync rsync://mirror.as24220.net/epel
rsync: failed to connect to mirror.as24220.net
(126.96.36.199): Connection refused (111)
rsync error: error in socket IO (code 10) at clientserver.c(122) [Receiver=3.0.9]
Therefore the crawler falls back to HTTP scanning which is not optimal.
If possible, please re-enable the rsync server. Thanks.
it also seems you are not deleting old files on your mirror. Not really
important but also not necessary to keep all those old repo databases
