It is because we prelaunched a ton of simultaneous servers to meet demand. For some reason amazon thought that meant to make a ton of unwarmed copies of the server build image and we can't tell which is which. We actually had them running all last night and they gave no indication of a problem. We are warming them all now and are trying to get servers back up in the next 1-2 hours.
The issue is that when the servers change tracks they aren't warmed so it takes like 10+ minutes and all the clients drop.
