Nordic data center provider atNorth, has just announced the expansion of its data center facility in the Mjölnir campus, located close to the Keflavik International Airport, Iceland.

atNorth has now commenced construction for the extension, adding the eleventh building to the campus with the provision of an additional 4MW power capacity, further increasing the data center facility floor space by 10%.

“This latest building is another milestone in the remarkable Mjölnir DC story. In just two years, soaring customer demand has seen the site more than double in size – and ongoing talks could see another two buildings added in the near future,” the company stated in the announcement.

“This unconstrained growth potential coupled with opportunities to better meet their social and environmental obligations are all reasons that companies are choosing Iceland for their HPC hosting. atNorth provides predictable, long-term costs to help with future planning and to ensure that clients are achieving best value from their budgets.”

The Mjölnir facility is one of the two data center campuses operated by atNorth in Iceland through its partner, Thor DC, based in the Reykjavik capital area, which offers Tier III capabilities for data center workloads.

In terms of energy supply, the Mjölnir data center campus is powered by 100% renewable energy sources, leveraging about 80MW of power supply drawn directly from geothermal and hydro energy sources. The Mjölnir facility also makes use of Iceland’s lower ambient temperatures to assist with data center cooling – complimenting the performance of liquid-cooled systems.

This expansion follows the development of atNorth’s latest data center SWE01: SIF DC, a new $72 million data center facility in Stockholm, Sweden. The new Stockholm data center is designed to offer a total IT load capacity of 11.2MW. Spanning 6,400 square meters, the Sweden data center facility is also atNorth’s flagship AI and high-performance computing Infrastructure-as-a-Service (IaaS) project.
