A directory over SSH can be your git server. If your CI isn't too complex, a post-receive hook looping into Docker can be enough. I wrote up about self hosting git and builds a few weeks ago[1].
There are heavier solutions, but even setting something like this up as a backstop might be useful. If your blog is being hammered by ChatGPT traffic, spare a thought for Github. I can only imagine their traffic has ballooned phenomenally.

Doesn't post-receive block the push operation and get cancelled when you cancel the push?
> The origin of a git repo is more or less just the contents of the .git directory in a remote location. That's it. You don't even need to run a git server if you're happy enough using ssh for transport.
Yeah. You probably do want to make sure you turn your .git/ into a "bare" git repository but that's basically it.
And it's what I do too: an OCI container that gives me access to all my private Git repos (it sets up SSH with U2F so I get to use my Yubikey to push/pull from various machines to those Git repos).
