Kolo: SE3 Piteå

The Kolo SE3 Piteå data center carries a storied legacy as a pioneer of the Swedish data center industry, beginning in 2004 when it was founded under the name Fortlax. The facility gained international recognition for its unique "military-grade" roots; its flagship site was originally constructed by the Swedish National Defence Radio Establishment (FRA) in 1991, providing a foundation of extreme physical security and EMP shielding that remains a core feature today.

In 2019, the site was acquired by EcoDataCenter, which integrated its high-security reputation with a focus on 100% renewable energy and "climate-positive" operations.

In early 2025, the facility was acquired by CapMan Infra to serve as a cornerstone of the newly launched Kolo DC platform, continuing its evolution from a regional high-security fortress into a modern, Arctic-cooled hub for high-density AI and HPC workloads.
