I definitely don't recommend cloning from review.o.o, better to rely
on https://opendev.org/openstack/nova in your origin remotes.

That https://review.openstack.org/p/openstack/nova URL is "just
another replica" like opendev.org and github.com (the /p is directed
to a local copy Gerrit is replicating to a local copy on the
server's filesystem).

Gerrit can't guarantee consistency for its replication tasks, so it
can certainly happen. I think we had plans to remove that /p replica
anyway (it's going to potentially conflict with some URLs for newer
Gerrit versions), but generally if you notice a discrepancy between
and https://opendev.org/openstack/nova do let us know, we've been
trying to get on top of a race condition in our Gitea updates where
Gerrit will silently fail to replicate refs to some of the servers
while they're in the middle of restarting.
