The datacentre, dubbed a "megacentre" by the firm, was opened on November 2008 and replaced a 15-year-old facility. It was designed by Keysource, a datacentre specialist contractor, and has a PUE rating of 1.148. This was achieved in part through the use of cooling techniques such as filter bags (pictured), which filter warm air and send it back through a water-cooled gate for reuse.
