Yes I agree that they probably did not fully shutdown the servers as they have NEVER lost their power. If you look at the grid they are on (I forget the JP site i was looking at) they have a few hospitals, government buildings & the train station within 2 blocks.

But on another note TEPCO is undecided if they will or won't be doing anymore blackouts. They have been able to produce enough power to keep everyone going (with saving electricity still) and have also just added some more available power a few hours ago.

It will be a coin flip whether SE is going to just flip the switch back on for us or wait it out until Friday (the last day of blackouts that TEPCO announced if they even happen). Japan is recovering a lot faster then anyone anticipated so it is safe to say that we will not be waiting 2+ months but only 1-2 more weeks (worse case scenario)

Just a little food for thought ^^
