UPDATE: it's back
The pretty (and utterly weird) NERV Power Supply Monitoring System now reports that TEPCO is generating 'NaN kilowatts'... (x_x)
I guess I have no recourse but to visit 東電's pathetic official offering, where I am told that we've got "5,270 10 thousand kW" available to sustain human society in Tokyo today.
Parsing that isn't made any easier by the sweltering heat and lack of civilized air conditioning, let me tell you...
