In short, no, unless you think people replacing broken hardware or patching bugs in your software can be automated.

Your question is too vague. Github is up enough that I don't care. However, it's down enough I wouldn't want to not be able to deploy because it's down. Therefore, I may mirror my repo somewhere else. That's easy because git is decentralized. It's a lot cheaper than running some alternative that I guarantee is always running. You can do this by simply pushing to a mirrored remote branch.

If you're just interested in the subject, research high availability.
