The process began at 8.30am Pacific Time (4.30pm in the UK) and is scheduled to last roughly three hours. But you know how these things can go, so FIFA 15’s Ultimate Team portion may not return at 11.30am/7.30pm on the dot.
Update: As you may have expected, the maintenance has been extended to 2pm Pacific/10pm UK.
Update 2: It should be back now. Rest of the original story follows.
This maintenance session also affects the web app and mobile apps. You won’t be able to use those either while this is going on. EA isn’t giving any precise details about what this maintenance entails, so it’s probably safe to assume they’re not introducing new transfer market features or anything.
