In the wake of the massive quake and tsunami that struck Japan on Thursday evening, Square Enix have shut down servers to online MMO titles and online services, Final Fantasy XI, Final Fantasy XIV and PlayOnline, in order to conserve power.
Due to the continuous earthquakes occurring in the eastern regions of Japan since Mar. 11, 2011, the power companies in Japan have encouraged everyone to cooperate by conserving as much energy as possible as it is feared there will not be enough power supply. Based on the current situation, we have decided to shut down the game servers temporarily, and therefore to suspend services of FINAL FANTASY XIV, FINAL FANTASY XI, and PlayOnline temporarily.
The services will be temporarily suspended for at least a week starting on Mar. 13, 2011 3:00 (PDT). We will provide an update regarding the reinstatement of the service as additional information becomes available. In connection with the temporary suspension of services, players will not be billed for any PlayOnline service throughout the April billing cycle. Additional information regarding this matter will also be posted as it becomes available.
We apologize for any inconvenience this may cause, and thank you for your understanding of this unusual situations.
Servers will be down for a week starting today on March 13, 2011.
