The attack started between 05:35 and 05:40 CDT yesterday, when the user count jumped from 387 to 909. The attack lasted until around 16:05 CDT (4 PM), when the user count dropped from 787 to 53. For the duration of the attack the user count hovered around 2000, with a maximum of 2591 users at 08:35.

When the attack concluded, I and others were unable to log in, getting a password incorrect error. I received no email notifications after being PMed, and attempts to create new accounts resulted in a blank screen. Some users were still logged in and able to post, but attempts to change passwords were unsuccessful.

The site is back up, but I’d update your passwords.
