It was hacked at 7:30am CST yesterday. Some (insert expletive) ran queries on the member's database and removed all of the members, basically destroying the whole site. This wasn't some security highlighting exploit, it was purely malicious and destructive. I am in the process of restoring from backups so only some 6 hours should be lost. I will however, need to change all of my passwords because the hacker somehow gained access to my super-admin account. I am hopeful that I will get the site back up and running at some point today.
