That maintenance is conducted as conveniences Japan seems quite besides the point. The US East Coast is a sizable portion of the game's subscribers repeatedly inconvenienced not only by the baffling decision to not rotate maintenance timings in a sane, responsible manner that, if not equalizing the impact across the board, at least offers an occasional reprieve to the one group of players saddled with the worst of the maintenance burden, but also by frustratingly poor routing that too often causes East Coast players to have worse ping to US servers than do players connecting from Southeast Asia. It is not as if the revelation that Square Enix is a Japanese company - quelle surprise! - somehow eases these concerns. Nor does it satisfactorily explain them.

I also understand that programs like Slack, Skype, Discord exist to help large teams communicate that may not be located in the same region or time zone, and co-ordinate efforts like server maintenance. For that matter, if real-time communication is an issue across time zones, a still older technology known as Email may be used to schedule the operations of a multinational company such as is convenient for ALL of their customers, without requiring they co-ordinate in real time maintenance of servers that, despite not sharing players, content, or physical server space, must go offline simultaneously.
