You have all been blessed with my fantastic theories about the real reasons the power went out in the Northeast last August, so I won't repeat them again.
I have always found it curious though, how the primary alarm system and its backup both failed within 14 minutes of each other at the most critical time. This was one of the primary factors of the blackout, as operators were not alerted to a catastrophic overload condition brewing until the failed alarm systems were discovered offline nearly an hour later.
Well, it turns out there was a bug in the software that runs those alarm systems. (That software was not written by Microsoft, by the way. Turns out other companies also have the capacity to write buggy code.)
Looks like my cyberterrorism scenario is taking another blow to the head. Damn! Oh well, it made for a good story.
