Is this the case for all regions? I'm happy we talk about improving the
repomirror, and I agree that it might be time to stop redirecting to
arch mirrors, but only if we can make sure to provide proper global

I'd of course happily volunteer to use the repomirror in the future and
help fix any issues that crop up.

That sounds like a lot of extra work for something that could just be
gone by implementing the change proposed above. I think we should keep
this option in mind, but postpone it for now, and see if we still need
it. Of course, if we come to the conclusion that we are not yet able to
drop the arch mirrors, we can consider this as an alternative way to
make the repomirror more reliable.
