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
SK Telecom's sovereign AI cloud cluster at SK Broadband's Gasan AI Data Center in Seoul, launched 5 August 2025 with more than 1,000 NVIDIA Blackwell (B200) GPUs, built with Penguin Solutions for integrated AI data-center design and Supermicro for server procurement. Named after Haeinsa Temple, home of the Tripitaka Koreana. Selected by Korea's Ministry of Science and ICT for the government's Sovereign AI Foundation Model Project, and in mid-2026 became the first Korean AI infrastructure to earn KISA's Cloud Service Security Certification (CSAP) while in active government use rather than a test environment. Exact GPU count beyond 'over 1,000' and power draw are not disclosed by SK Telecom, so quantity is recorded as reported rather than exact.
