A power outage knocked out traffic signals across parts of San Francisco‘s Richmond District and Presidio on Saturday morning. This time, Waymo got out of the way before things went sideways. The company said it paused service in the area for about an hour starting shortly after the outage began, a precaution it says was informed by two earlier incidents — a December blackout and a Fourth of July fireworks celebration — that left dozens of its driverless vehicles stuck in the street. A Waymo spokesperson said there were no reported problems on Saturday, describing the pause as a chance to assess conditions on the ground before resuming rides. San Francisco Fire Department spokesperson Lt. Mariano Elias confirmed there were no known issues. The Waymo spokesperson said the company stayed in contact with San Francisco’s Department of Emergency Management throughout the outage, and that some service adjustments in the affected area remained in place as of Saturday afternoon. The outage began around 9:45 a.m., according to PG&E spokesperson Edgar Hopida, and initially affected about 9,400 customers in the Richmond and Golden Gate Park neighborhoods. The outage occurred during routine switching work between the N and K substations, done to let crews perform maintenance without de-energizing larger sections of the grid, Hopida added in a late afternoon update. PG&E said it will investigate further to determine what went wrong. An automated alert briefly and incorrectly told 120,000 customers they’d lost power — the result, Hopida said, of a notification system rolling the outage up to a larger protective device. The false alert stemmed from a data-transmission issue between SmartMeter and PG&E’s Outage Management System, Hopida said, which “communicated a much larger outage than was reality.” Power was restored to all but 2,500 customers by 12:10 p.m., Hopida said, and all customers
