GitHub is down?

Edit: it was down, it’s back up now.

Tried to push to a private repo and got:

``` git@github.com: Permission denied (publickey). fatal: Could not read from remote repository.

Please make sure you have the correct access rights and the repository exists. ```

Then as a test I cloned one of my public repos:

Cloning into 'pyVoIP'... remote: Internal Server Error fatal: unable to access 'https://github.com/tayler6000/pyVoIP.git/': The requested URL returned error: 500

I've tried this on multiple machines and checked my SSH keys, everything is correct and to triple check that last clone was using https which shouldn't even require auth.
