After Japan's 2011 earthquake, Square Enix voluntarily disabled servers to conserve energy due to the incapacitated state of the region's nuclear power plant. This led to a temporary halt of the Final Fantasy XIV, Final Fantasy XI, and PlayOnline games and services from March 13 to 25.[16][17] During the power shortage, air conditioning and lighting was reduced, and the subscription fees for Final Fantasy XI were waived for the month of April.[17]
