Data Residency

Where is your data stored and processed?

Nscale: Norwegian data centres offer EEA data residency with renewable hydropower. UK facilities planned. Customer workloads stay on Nscale infrastructure. Norway option provides strong EU data residency.

Nebius AI: Data centres located in Finland and the Netherlands—both EU member states. Inference and compute workloads remain within EU borders. Strong data residency story for European AI builders.
