Fedora mirror at mirror.digitalnova.at unreachable

[Adrian Reber]

There have been reports that the mirror mirror.digitalnova.at does not
work: https://pagure.io/fedora-websites/issue/833

I also cannot reach the mirror and have disabled it for now.
MirrorManager detects that the mirror is not reachable, but as the
reporting from the mirror (report_mirror) still runs, the mirror is
re-enabed and still active.

Could you have a look at your mirror and re-enable it in MirrorManager
(user_active) or let me know. Thanks.

Adrian
