Anti Terror Policy: Dispersal Takes Hold

"Making financial functions more spread out, and maintaining parallel functions in both downtown and suburban locations - known as the ''active/active'' model, as distinct from having one active site and one backup site - is seen as a possible deterrent against a terrorist attack. A financial firm's downtown office tower, or the floor of a stock exchange, makes a less compelling target if business can continue and there is no massive economic disruption, according to this theory."
