Those underground tunnels in Telford

Many, many moons ago I used to work for a company called EDS. They’re now part of HP Enterprise Services, but back then EDS owned several buildings in Telford, which is where I was based.

This is quite some time ago now, but I was wondering what had happened to all the underground tunnels connecting up those old buildings, and the underground data centres that weaved their way under the town. Anyone know? There’s very little on the web about it.
