A major blackout has struck Southern California leaving many Los Angeles residents in the dark.

According to the latest reports as many as 1.4 million people are in the dark and the power could remain out for up to 20 hours in some areas, though most should be restored more quickly. The blackout has also impacted areas of Arizona and Baja California.

Naturally there is speculation as to the cause of the blackout and immediate rumors of possible sabotage and/or terrorism but in all likelihood this is just the result of an overtaxes system and a hot summer day.
