In fact the very fact that your source control hosting service can be surpringly[1] unreliable is the best advertisement for git you could imagine.
In fact, if github disappeared from the internet today, all but the largest projects could just set up an ssh-accessible box somewhere and continue work (code review and issue interfaces notwithstanding, of course), probably with 24 hours.
[1] I work in github-cloned repositories almost full time. And sure, I remember a handful of times over the past 4-5 years where it's been down when I wanted to push something. I had no idea it was 50x/year! And that's because "working in a github-cloned repository" doesn't, in fact, require much contact with github itself.
