One thing that has become apprent is appengine, is designed to scale under real world usage.
So if your App went from 0/1 users to 500 in a matter of seconds, then the system wont work well. You need to ramp up the usage slowly. Even a slashdotting would result in a 'ramp' usage. Also 500 users coming from once source, might be a bit suspicios, and appengine could be weary of a DOS attack.
