About the project

Helsinki, Finland

Helsinki DC-4 combines Global renewable power with advanced liquid-to-chip cooling for GPU-dense clusters. The site peers with national research networks and offers dedicated zones for regulated public-sector workloads.

Free-air economisation and heat reuse keep annualised PUE below 1.15 even at elevated rack densities.

Technical capabilities

Connectivity

Carrier-neutral meet-me room with cloud on-ramps and diverse fibre entry paths.

Security

Layered physical security with biometric access, CCTV, and 24/7 on-site personnel.

Sustainability

Renewable power sourcing, heat reuse, and transparent efficiency reporting.
