The assumption that developer time is lost when Github is unavailable is wrong. The whole idea of Git being a distributed VCS that it does not require any connection to the main server (i.e. Github) to work with a local copy of the repository. If Github is down, I can still do my work locally and then push changes to Github when it's back online. The only case when I may get blocked, is when I need to fetch project dependencies hosted on Github to do the initial build of my project, which doesn't happen very often.
