If you're looking for a self-hosted solution to keep you from becoming overly dependent on Github, take a look at Gitlab [1].
Since you're using Git, all those repos are presumably backed up on individual development machines. Or you could easily write a cron job to mirror them every day or so.
The real problem is other content like issue tracking, wikis, and pull requests. If keeping these is important, you may be locked into the platform, at least as far as existing projects are concerned.
