Check frequency of namespace renames / delete / creates on GitLab.com
In https://gitlab.com/gitlab-org/gitlab-ce/issues/40970#note_51477543 @stanhu points out:
We do have an event log that tracks every project transfer, so one thing we could do is prioritize checking of namespaces/projects that have been renamed and see if the data supports our theory.
Context: "[When using Geo], without hashed storage, there is a definite possibility that through some combination of project renames/transfers/etc. a user may lose access on the secondary to the repository or another user may gain inadvertent access to it."
