Cheatsheet for continuing work when Github is down:

    1) ssh myserver.com
    2) adduser git
    3) sudo su git
    4) cd $HOME
    5) mkdir .ssh
    6) Add people's public keys to .ssh/authorized_keys (in /home/git)
    7) git init --bare myrepo.git
    8) Push and pull to git@myserver.com:myrepo.git

Voila!
