Operating as a "Twin-Site" ecosystem in the heart of Stockholm, Kolo SE1 Atlas and Kolo SE2 Tellus provide a high-security, ultra-low latency foundation for AI and enterprise workloads. SE1 Atlas serves as the primary urban anchor, specifically engineered to support high-density GPU clusters with 2N power architecture and a pioneering heat-recovery system that warms thousands of local homes.
Located just 10 km away, SE2 Tellus acts as a direct mirror, offering identical 50 kW per cabinet cooling capabilities and geographic redundancy to ensure seamless failover and data replication.
Site History
In 2020, the Swedish operator EcoDataCenter acquired these two Stockholm facilities, which together offered 1,000 square meters (approx. 10,800 sq. ft.) of white space. The platform underwent a significant transition in 2025 when Kolo DC expanded into the Swedish market by acquiring three EcoDataCenter sites, including these two strategic Stockholm hubs, to form their current AI-ready infrastructure.
