Another key anchor for the area is the New York Stock Exchange. City authorities realize its importance, and believed that it has "outgrown its neoclassical temple at the corner of Wall and Broad streets", and in 1998 offered substantial tax incentives to try to keep it in the Financial District. Plans to rebuild it were delayed by the September 11, 2001 attacks. The Exchange still occupies the same site. The Exchange is the locus for a large amount of technology and data. For example, to accommodate the three thousand persons who work directly on the Exchange floor requires 3,500 kilowatts of electricity, along with 8,000 phone circuits on the trading floor alone, and 200 miles of fiber-optic cable below ground.
