To give you an idea just how much phone traffic was being routed through that building, they had a major power failure at that site and it took down most of the north eastern US's phone network:

On September 17, 1991, management failure, power equipment failure, and human error combined to disable AT&T's central office switch at 33 Thomas. More than five million calls were blocked, and the Federal Aviation Administration private lines were also interrupted, disrupting air traffic control to 398 airports serving most of the northeastern United States.
