BBC News is reporting that TEPCO (the power company in Japan) has announced planned power outages in Japan until the beginning of April (these are known as rolling blackouts or mandatory rolling blackouts in the US). I am guessing it these blackouts that have prompted SE to shut down service, as much as it is a desire to help their nation. Though SE has said "a week or more," TEPCO's announcement might shed a little light on what we can expect so I thought I would throw this out there.
