Nightfall is descending on the 620 million Indians without government-supplied electricity in the biggest blackout in history. Already, the collapse of three regional grids has stalled hundreds of trains, caused massive traffic jams and even stopped crematoriums half-way through burning dead bodies. While Indians are no strangers to blackouts (backup generators and candles are in widespread use), a blackout of this scale has never been seen. Below are scenes of Indians coping with the darkness:
