Could you purge all traces of repos cdrichards/mauka.net and cdrichards/mauka-net?
I tried to delete the first, which failed with a 504. Then I tried to rename it to the second, which also failed. Now the second name appears to be used (I can't re-migrate from GitHub to it) and the first gives me the following error:
"The Git data underlying this repository cannot be read. Contact the administrator of this instance or delete this repository."
