Fans of either of the Final Fantasy MMOs will be pleased to hear that Square Enix’s online servers will be up and running again on the 25th of March, 4pm PDT. The service was temporarily shut down following the Tohoku earthquake in Japan. 11.6% of the power used by Square Enix’s Tokyo office is used on these servers and in order to resume operation they have turned off their air conditioning and reduced their office lighting.
Thanks to Siliconera for the info.
