Well. That was interesting.
A bug in ATP was triggered (by me) tonight and it made an infinite loop in the most catastrophic way. It brought the site completely down and had me scrambling to even figure out what happened. Thankfully I'm not a complete noob at programming and I isolated and disabled the block of code that caused the problem.
Sorry for any inconvenience anybody suffered. Know that while you were panicking with ATP withdrawal, I was panicking with trying to get it back online.
I don't anticipate any further problems tonight.
