I think someone should write a tutorial about how to continue working while Github goes down. If you're trying to deploy from a master branch on GitHub, this could be an issue, but if you're just trying to share projects between peers, this should be a that big of a deal right?
We found out the hard way that directly deploying from github might be a bad idea. I wrote a little web service that receives notifications via hooks when code is tagged and rehosts the tarballs in S3 for deployment. it's been rock solid in production.
