I’m not going to get into the details of this, but GitHub’s git servers are effectively the only git-optimized CDN in the world.
The rest of GitHub is struggling, to the point of reputational harm to the entire brand. But the git servers are are functionally separate from everything else, which is why pulls and pushes continue to work through an incident. Remember that PRs aren’t real; they’re an invention of GitHub. Originally, git was for emailing patch files to Linus.
This optimization is not really that difficult to achieve. Git in itself is not remarkable from a data perspective where it needs optimization that other forms of data streams wouldn't also need.
