Thanks for the reports here, this is a top priority for us today now that we’ve cleaned up most of the DB load from yesterday afternoon and evening.
We believe we’ve identified the cause and are exploring fixes that can be deployed in a timely manner. This is a problem with the World Servers so adding more Realms wouldn’t help (and adding more world servers won’t help either, this is a code issue and not a hardware issue). We’ll get to the bottom of it.
