The extended PC maintenance postponed earlier this month has been rescheduled for next
Tuesday, January 28, 2020 at
4:30 AM PST / 12:30 PM GMT. NA and EU servers are expected to be down for up to 12 hours on that date.
While we're continuing to make strides reducing downtimes for game updates and standard maintenance, next week's extended downtime is necessary to complete a one-time data migration and provide needed upgrades to our server hardware in NA and EU. We're getting the news out to you now so you have as much heads-up as we can provide, and will do everything we can next Tuesday to wrap maintenance as quickly as possible. Once maintenance concludes and we confirm everything running smoothly, we'll schedule the corresponding PS4 maintenance in the same server regions.
