Virtus Data Centres, a UK-based data centre colocation provider, has announced the launch of two new facilities to create London’s largest data centre campus.

The two buildings, known as VIRTUS LONDON5 AND LONDON6, will total 34,475 metres squared, and will aim to deliver 40 megawatts of IT load with the secured power capacity to increase to 110 MVA.

The move will ‘further strengthen’ Virtus’ claim as the largest hybrid colocation provider in the London metro area, according to the company, with the site being located 16 miles from central London, and 7 miles from Slough on the primary fibre routes.

“As we move with our customers into an increasingly digital future, we help them deliver high performing applications and content,” said Neil Cresswell, CEO of Virtus Data Centres in a statement. “We provide fast, seamless connectivity to networks and public cloud, along with the capacity for vast data storage and compute processing power – all for lower costs.

“This investment in LONDON5 and LONDON6 means we can grow with our customers and help them achieve their ambitions,” Cresswell added.

Even if the site ends up being London’s biggest, it pales in comparison to what is planned as being the largest in the world, in Norway. Last month, Kolos announced the launch of a proposed site, in the Norwegian town of Ballangen, inside the Arctic Circle, that could cover 6.46 million square feet and stretch across four storeys.

The largest data centre in operation today is in Langfang, China, at 6.3 million square feet, while a site in Tahoe Reno, Nevada, is set to be 7.2 million square feet when it becomes fully operational.
