Based on your "And" instead of "But" -- I didn't mean to imply they should keep them running.
I'm saying EA will take a game's server down even if it's running normally. Setting up a temporary server in this case also means transitioning over to this Game Ranger technology, which is likely non-trivial. So it not only takes whatever server resources were already in place, but also needs code and QA time dedicated to making sure it doesn't shit the bed.
