They promised to fix the outage in some hours. The blackout also affected businesses, schools and tourism. The power cut did not affect San Francisco International Airport, and the U.S. Department of Homeland Security but many abnormal situations occurred. Many systems went down. The stoplights were not working in the streets. Trains streamed through the Montgomery Street station as the outage prevented them from stopping. At Saint Francis Memorial Hospital all non-essential appointments and procedures had been canceled. The stores were in darkness. Restaurant and coffee shops closed. At least several blocks of the financial district lost electricity.
Earlier in the day, an outage also hit New York, where subway riders found their commutes temporarily halted. Another outage occurred in Los Angeles. It is not yet evidence that they were connected by anything more than coincidence.
