Warning: It's VERY long.
It seems that, though the trigger may not be relevant, the vulnerablities pointed out by the Y2K Prophets were accurate.
U.S. intelligence agencies have upgraded their warnings about al Qaeda's use of cyberspace. Just over a year ago, a National Intelligence Estimate on the threat to U.S. information systems gave prominence to China, Russia and other nations. It judged al Qaeda operatives as "less developed in their network capabilities" than many individual hackers and "likely to pose only a limited cyber-threat," according to an authoritative description of its contents.
In February, the CIA issued a revised Directorate of Intelligence Memorandum. According to officials who read it, the new memo said al Qaeda had "far more interest" in cyber-terrorism than previously believed and contemplated the use of hackers for hire to speed the acquisition of capabilities.
"I don't think they are capable of bringing a major segment of this country to its knees using cyber-attack alone," said an official representing the current consensus, but "they would be able to conduct an integrated attack using a combination of physical and cyber resources and get an amplification of consequences."

Blacked out Nearly all 355,000 JEA customers left without power
About 4:30 p.m., two large electric lines heading east out of the Brandy Branch Generating Station near Baldwin shut down when circuit breakers tripped on both lines. It's unclear why those trips occurred, but the breakers are designed to shut down portions of the lines to prevent further faults from the actual point of trouble.
When those lines shut down, electric lines heading west out of Brandy Branch picked up the load along with other electricity coming from Georgia and redirected that flow back into the city grid over two other lines. Electricity was still flowing freely and not overloading the grid into the city.
A short time later, there was an unexplained transformer fire at the Kennedy Generating Station north of Talleyrand and the generator at the plant shut down. Electricity generated from Kennedy had been flowing in the two operating transmission lines along with the electricity from the Northside Generating Station and the nearby St. Johns River Power Park.
