Brokerages had backup DC's in Journal Square(IIRC) long before 9/11. It was apparently a favored location as you could draw power from 3 'independent' grids. After 9/11, a number of them didn't bother transitioning back to Wall St. I worked on Wall St. during the 90s, and was really shocked how much of a ghost town it had become even 3 years after the attack.
