Power outages in San Francisco

Yesterday afternoon a major power outage in San Francisco took many popular websites down. Sites affected included CraigsList, TypePad, and LiveJournal. The most surprising thing in all of the outages, was not that the power went down, but rather that the backup systems for many of these sites failed completely. Companies spend fortunes to provide backup power systems and redundancy for their servers. To have all of that redundancy fail at the same time is unprecedented. It just shows us how fragile our information infrastructure is.
