Deep dive: How Nebius and Nscale build GPU clouds
Also known as Nscale Keflavik; Verne Iceland GB300 deployment
Operated by Nscale at Verne Iceland Campus (Keflavik) .
Phase 1 seed dataset, compiled by hand. These rows were built from public operator, laboratory and vendor sources. A mechanical second-reader pass has since fetched every cited source: 1092 of 1153 systems have a readable citation that names them, and 40 are genuinely weakly sourced. Every claim carries its source and a confidence tier. Treat anything below verified as a lead, not a citation.

What this machine is made of
One row per supplier relationship. “Supplier at build” is the company that shipped the part at the time; where that company has since been acquired, the parent it rolls up to today is shown beside it. That distinction is what makes ticker-level aggregation possible across a thirty-year dataset.
| Role | Part | Supplier at build | Quantity | Confidence | Source |
|---|---|---|---|---|---|
| Integrator | - Nscale deploys and operates the GPU capacity under a 15 MW lease at Verne's Iceland campus | Nscale | - | Reported | nscale.com |
| Integrator | - Verne hosts the deployment at its Keflavik campus; first phase delivered with Computacenter, Lenovo and Vertiv per BeBeez | Verne | - | Reported | verne.cobebeez.eu |
| Accelerator | NVIDIA GB300 NVL72 Accelerators NVIDIA GB300 NVL72 racks in the first liquid-cooled phase; approximately 4,600 GPUs planned in total (85% liquid cooled, 15% air cooled) | NVIDIA | 4,600 reported | Reported | nscale.comverne.co |
AI datacenter metrics
Figures beyond an accelerator count, each with who stated it. What can and cannot be compared across AI datacenters.

|---|---|---|---|---|---|---|---|
| Hydro | Verne | - | operating | 2026-10 | Operator stated | Verne Keflavik campus (over 140 MW) states it runs on hydroelectric and geothermal power; Nscale deploys 15 MW there. No split by source disclosed. | verne.conscale.com |

The read
Nscale's 15 MW lease at Verne's data center campus in Keflavik, Iceland, announced in November 2025 for approximately 4,600 NVIDIA Blackwell Ultra GPUs deployed through 2026, 85 percent liquid cooled and 15 percent air cooled. BeBeez (24 April 2026) reports the first phase, 7.5 MW across 128 racks including 64 liquid-cooled GB300 racks, was completed on 23 April 2026, so the 4,600 figure is the contracted target and not a confirmed installed count. Epoch AI's directory estimates about 2,300 B300 chips and 5 MW of IT power today, rising to about 15 MW by the end of 2026. Separate from Nscale's Svartisen cluster at Glomfjord and from the Microsoft-tenanted Narvik and Loughton rows. No FLOPS or HPL figure has been published.
