GitLab seems quite poorly

[Matthew Pickering]

I don't know what has changed since yesterday but pushing new branches
to GitLab is broken.

The two most recent branches pushed to origin 404 when you click on the link.

https://gitlab.haskell.org/ghc/ghc/branches

https://gitlab.haskell.org/ghc/ghc/tree/wip/mp/15646

I also pushed some commits to a fork and the MR which they appear on
didn't update at all. Perhaps a symptom of the same problem.

Also a recent MR by Ben complains of the source branch for the MR not
existing.  https://gitlab.haskell.org/ghc/ghc/merge_requests/625

The summary is that GitLab seems unusable at the moment. Did you
fiddle with anything recently Ben?

Cheers,

Matt
