When I worked for the Halifax a few years ago, they had quite extensive DR capability with dark fibre replication between two data centres. One in halifax and one in bradford. In theory, operation was site neutral and all internet facing systems were supposed to be active-active across the two sites.

The core banking system is an IBM mainframe with lots of SQL Server and a few Unix oracle satellite systems. I suspect Niall is right and they neglected to keep the satellite systems' DR capabilities up to speed.
