Tencent Gui'an Seven Star Data Center
Operational; the organisation this record names is not established in any role by its cited source
Tencent's flagship Guizhou self-built data center, sited inside a tunneled mountain in the Gui'an New Area, Guizhou Province. The 51-hectare campus carves more than 30,000 m² of tunneled volume out of a ~100 m hill (five tunnel entrances, each ~15 m high and two floors); construction broadcast on CCTV state media April 2018. Designed to civil-air-defense standards (effectively bomb-shelter-grade), the facility was reported by South China Morning Post (May 2018) and DCD as Tencent's most secure DC, hosting WeChat / Weixin core infrastructure. Capacity discussed publicly: ~300,000-server total, with ~1/6 of servers (~50,000) inside the five cavern halls hosting Tencent's most-critical big data. Total site area ~470,000 m² per Idcnova-Media reporting on the completion of the Seven Star DC.

Methods and sources
Ownership roles
Title identifies the legal owner of the site; operation identifies who runs it. AI-hardware ownership follows the catalog’s attribution of the machines inside, whose owner may lease the facility.
Each role requires its own attribution. An operator named in a source supplies evidence of operation only.
Parent companies
Ownership checks start with each company named at the site and follow recorded parent relationships. A company holding several roles is checked once. Its linked company page lists the relationships and their sources; further parents may remain undocumented.
Level 1 identifies a company at the site, level 2 its parent, and each further level another parent. Export-control designations and government investments are assigned to the company concerned.
Missing values
Unrecorded roles remain blank. Findings whose company position is unresolved stay in the list with that position labelled unknown.
Publication limits
Subscription corporate data helps identify parent relationships and sovereign investments. Publication is limited to relationship classes and supporting public sources; licensed records, identifiers and values are withheld.
