Sure.

GEANT is also Internet2. So it seems to be correct that you have selected
that checkbox. MirrorManager downloads once per day the list of
Internet2 networks

https://github.com/fedora-infra/mirrormanager2/blob/master/utility/mm2_get_internet2_netblocks

and based on this clients on Internet2 are getting mirrors on Internet2
with a higher priority.

If you enable ASN clients then MirrorManager tries to redirect clients
within the ASN preferred to mirrors which have it enabled. So I would
say that you can enable it.

Your mirror has been automatically disabled because it failed crawling 4
times in a row. You have already done everything to enable crawling.

I manually started a crawl of your mirror so that in a few hours you
should see clients being redirected to your mirror again.

I am also pretty sure you can remove the gopher URLs from your mirror
entry.
