Repo access problems

[Tollerton, Rich]

My apologies in sending this email via Outlook, which is not how I normally
interact with mailing lists; I have not yet been able to devote the time to
resurrect my plaintext email setup.

I'm having problems accessing the GMP repository, either for HTTP browsing or
for cloning. It isn't impeding me, but I figure I should say something in case
the maintainers don't know about it yet.

I navigated to https://gmplib.org/repo/ and began browsing one or two branches.
But even before I was able to navigate off of the branch landing pages, I
started receiving 403 Forbidden errors. I'm not seeing 403s browsing the rest of
the website, and downloading gmp-6.3.0.tar.xz appears to work fine. An hg clone
from the same machine also fails with a 403. But when I tried to clone from
other machines -- one of which is behind the same NAT as the first machine, and
the other is a VPS on a completely different network -- the clone proceeds
significantly further than that before failing with what appears to be a
connection-reset-by-peer sort of error:

$ hg clone https://gmplib.org/repo/gmp/
destination directory: gmp
requesting all changes
adding changesets
adding manifests
adding file changes
transaction abort!
rollback completed
abort: HTTP request error (incomplete response)
(this may be an intermittent network failure; if the error persists, consider contacting the network or server operator)

The only salient difference I'm able to identify with the machine that's
receiving 403s is that it's running MacOS and the others are running Linux.
(Which almost can't not be a red herring IME.)

Nominally I'd guess that something else in my org is abusing gmplib.org that I'm
not aware of. But the fact that another machine behind the same NAT doesn't seem
to be having the same problem sort of shoots down that hypothesis.
(Nevertheless, if 130.164.0.0/17 *is* giving the server any guff, I will gladly
make sure the responsible party gets yelled at.)

Thanks.
