By the numbers: Colt datacentre

A look at the numbers behind Colt's flagship facility for modular datacentres, London 3 in Welwyn Garden City, which features the company's own design

The new processing halls within Colt's large datacentre on the fringes of London are designed to offer a low PUE, combined with a short build time and ease of installation.

The London 3 facility is the flagship for Colt's new method of building modular datacentres. The company plans to roll out the design method across its European datacentres, including ones in its other core markets of France and Germany.
