A massive power outage that left millions in the dark across portions of the southwestern United States and northwestern Mexico eased early Friday, with the power back to all 3.5 million residents of San Diego who had gone without electricity for hours.
The outage was not related to terrorism, officials said. It may have begun with work at an Arizona power plant that provides some electricity to California customers.
At its peak, more than 5 million people in California were without power, along with others in Arizona and portions of Mexico. It was unclear how many people remained without power early Friday.
California officials urged residents to conserve power all day in an effort to protect what San Diego Gas & Electric Co. Vice President David Geier called a "fragile" power system.FULL STORY
