I apologize for the recent down-time - I contacted Dreamhost about it and just received this reply:
I looked into the issue and there was a problem with the permissions on the server. I corrected this for you and everything is working fine now! If there is anything else you need help with, please let me know! Thanks! Have a great day!

It looks like whatever they did worked, as BGDF is back up and running again! I'll delay posting the BGDF winner so that people who tried to vote and weren't able to log in can do so!
