A major power outage hit San Francisco today affecting central San Francisco. An estimated 9,000 people are without juice. According to Andrew Dalton at SFist's western headquarters, "a couple of PG&E crews are at Hayes and Baker staring up at power lines and looking dumbfounded." The outage occurred at around 9:40 am.

PG&E says that there's no estimation as to when power will be restored. We'll update as soon as we know more.
