There was a complete power outage in several towns at the same time just a couple days ago at 530 PM in the Southern California mountains. ( Check socal mountain news ) No reason was given for the outage. Strange considering there were no weather problems and power went out all over here at the same time. Oh, there were also a couple of loud booms when it went out. Although I didn't hear them when it went dark suddenly,my neighbor and others up here did.
