Here’s why black-outs in 3 major US cities were almost certainly related

Yesterday, morning power black-outs hit three major US cities in two time zones. Areas of New York, San Francisco and Los Angeles were hit by the still unexplained power cuts.
San Francisco’s power supply is controlled by Pacific Gas and Electric, most of Los Angeles is controlled by the Los Angeles Department of Water and Power while other areas are controlled by Southern California Edison and much of New York City is controlled by ConEdison.
