I use Github professionally, and for my open source projects. The visibility of a project on Github is hard to beat, and is often found just because it's on Github. Outages usually come on the front-end, and often I've been able to push to Github within minutes of finding an outage. That said, we're a small company with almost no remote collaboration on a given project, so outage doesn't affect us much. However, for my serious, closed-source projects (that I might want to become products) I use Bitbucket. So far I've experienced no outages.
