i heard they did it to continue griefing en mass, it took 2 full weeks for ironforge.pro to update and show the horde have left, and NOW the alliance want to leave to another equally high population server because their favorite punching bags are all gone it was a horde exodus and the sweaty alliance NEED something to hit.
people did NOT escape the queue timer, thats evident because people are still hopping over in droves with no queue timer present.
horde fled, alliance chased after them.
