When the Ultimatum league started this morning, it was immediately apparent that the login queue was moving quite slowly. We are investigating this, and so far it appears that the reason is that this league's character migrations (which are a process that runs when a character logs in, to convert it to the new internal version) are much slower than normal.

 

Users are getting in and the game is stable once they are through the queue, but it's going to take a while for the queue to clear and we're very sorry about that. We're acutely aware that a similar problem occurred last league launch and we thought we had resolved it.

 

Queue processing should speed up as more characters are converted, and we are trying to find other solutions that will help in the meantime.

 

Once again, we're very sorry about the delayed start to the league for most users. We will make sure that this never happens again.

 

We will update this thread as more information is known!

 

EDIT: We have a plan! This may result in people not having past league progress in Standard until we can catch up with that, but should massively speed up the queue for people logging in to Ultimatum (which is 99% of users right now). Will keep you updated.

 

EDIT2: Okay, so that plan sped up the queue by a lot. We're keeping an eye on stuff very closely .
