In my experience most Rails deployments and CI setups depend on Github being up. While it's possible to bundle and copy code on deploy rather than checkout from the server, most projects don't.
So of course you can continue developing locally, but if Github is down, it means the release/ci process is likely broken. I'm not saying this is Github's responsibility, but it's a reality for many people. It's another sales point for Github Enterprise.
