It’s more karma whoring than anything else, this post doesn’t add anything except that GitHub is down and people who care about GitHub already know it, and those who don’t care, well, don’t care about this post.
I just noticed that a repository wasn't working, but hadn't put it together that the entire site might be down... so the karma whoring was useful for me.
It really is, I ended up checking here straight away, despite there being a link directly to the status page on the error pages of github.
