Is it known who at Github can access private customer repos?

I'd assume everyone who works there. They aren't encrypted or anything. If you have hardware access you have full github access.

But I can definitively say that any repo access is heavily logged. And this info is from like almost 10 years ago when I had first hand experience. I know they've upped their game in terms of repository access gating since then.
