NEBIUS AI Cloud — Mäntsälä Finland Data Center

NEBIUS (formerly Yandex N.V., renamed after separating international operations from Russian assets) operates a major AI cloud data center in Mäntsälä, Finland — approximately 60 km northeast of Helsinki. The Mäntsälä facility was originally built by Yandex to serve European cloud customers and has become a primary node for NEBIUS AI Cloud, which offers NVIDIA GPU compute (H100 clusters) to AI startups, research labs, and enterprises. Finland’s location provides natural cooling benefits, access to Nordic renewable energy (wind and hydro), and EU jurisdiction — important for customers who need EU data residency and GDPR compliance. NEBIUS positions itself as a cost-effective GPU cloud alternative to AWS, Azure, and Google, targeting AI training and fine-tuning workloads. The company also operates AI infrastructure in the Netherlands.
