VIRTUS Data Centres is a UK-headquartered colocation provider that owns and operates a portfolio of data centre campuses across London, and has expanded since 2023 into Germany and Italy. Founded in 2008 and now majority-owned by ST Telemedia Global Data Centres (STT GDC) with a minority stake held by Macquarie Asset Management (as of 2022), VIRTUS describes itself as a pure-play data centre owner-operator rather than a cloud company — customers rent racks, cages, suites or whole halls, with connectivity on-ramps to public cloud platforms rather than a VIRTUS-branded cloud product. As of 2024–2026 its London footprint spans campuses at Enfield, Hayes, Slough Trading Estate, Stockley Park and West Drayton, with a new AI-ready campus under construction at Saunderton, Buckinghamshire. Its European expansion includes two campuses near Berlin (Marienpark and the 300MW Wustermark Megacampus) and a first Italian facility under development in Cornaredo, near Milan.

Which VIRTUS facilities have documented AI or high-density computing capability?
London7 and London8 at the Stockley Park campus are described as built to support HPC with no supplementary cooling required and racks of up to 80kW, and the planned Saunderton campus in Buckinghamshire is explicitly billed as an AI-ready development designed for racks exceeding 100kW.
