NTT Global Data Centers is the colocation and wholesale data center division of NTT DATA, operating dozens of carrier-neutral facilities across the Americas, EMEA, and Asia-Pacific/India as of 2025-2026. Formed through the consolidation of acquisitions including RagingWire (US), e-shelter (Germany), Gyron (UK), and Netmagic/NetMagic (India), the company builds and runs its own campuses — from Sacramento, Ashburn, and Chicago in the US to Frankfurt, London, Johannesburg, Mumbai, Tokyo, and Bangkok abroad — rather than purely reselling third-party space. Its customer base skews toward hyperscale cloud providers and large enterprises, and it has been expanding gigawatt-scale campuses and deploying liquid cooling to accommodate rising AI/GPU density, notably introducing liquid immersion and direct-contact liquid cooling at its Navi Mumbai 1 facility in India. NTT positions itself among the largest data center operators globally by geographic spread, spanning more than 20 countries and regions.

NTT Data AI Data Centers

The clearest documented AI-related infrastructure at NTT Global Data Centers is at its Navi Mumbai 1 facility in India, where the company introduced liquid immersion cooling (LIC) and direct contact liquid cooling (DCLC) in 2023 — the first production deployment of these technologies anywhere in NTT's global data center portfolio. The project was done in partnership with a major fintech client and vendors including Sudlows and Dell, and NTT has said it intends to extend lessons from this deployment to other facilities globally. Beyond this specific site, NTT executives have described broadly expanding liquid cooling capacity across the network over 2023-2025 to support rising AI/GPU density, though most such statements do not name individual buildings.
