There are a number of different reasons that may qualify as an “overload” suspension.

In this case: in addition to the usual daily limits, there are additional triggers that kick in if you go WAY past the limits. If that happens, you’re not going to get another chance to fix it after 24 hours. Going over the limits by such a ridiculous margin means your site is out.
