In a previous life, for one org's "GitOps" setup, we mirrored Gitlab onto AWS CodeCommit (we were an AWS shop) and used that as the SoT for automation.

That decision proved wise many times. I don't remember CodeCommit ever having any notable problems.

That said: if you're using GitHub in your actual dev processes (i.e. using it as a forge: using the issue tracker, PRs for reviews, etc), there's really no good way to isolate yourself as far as I know.
