I understand unplanned and off-schedule maintenances can be inconvenient, and we strive to keep these from happening as much as possible, but unfortunately they will happen on occasion with live service game at scale. This particular maintenance came in extremely hot, and we let players know about it as quickly as we could. Unfortunately because of it’s necessity, there wasn’t a timeframe we could leave open to use to let players know days in advance; as stated in the notes, infrastructure adjustments needed to be made ahead of our update next week, which meant doing this as quickly to prep and monitor was a requirement.
