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.

The read
A 10 MW cluster of NVIDIA H200 GPUs that Nebius colocates at Verne's data center campus in Keflavik, Iceland, announced on 11 March 2025; Verne calls it the largest single implementation in its Iceland history. Nebius's own blog says the capacity was expected to be fully operational by the end of March 2025 and gives the 10 MW figure; the H200 model comes from Verne's release. Neither page gives a GPU count, so quantity is left blank, and no fetched page confirms the final go-live date. Powered by Iceland's hydroelectric and geothermal energy. It has never submitted an HPL result.
