ST Telemedia Global Data Centres (STT GDC) is a Singapore-headquartered colocation provider operating a global platform of over 130 data centres across roughly a dozen countries in Asia Pacific and Europe, as of 2026. The company grew through both organic construction and acquisitions — most notably taking a majority stake in Tata Communications’ data centre business to form STT GDC India in 2016, and fully acquiring UK-based VIRTUS Data Centres in 2017 — and operates locally under the STT GDC brand across Asia and the VIRTUS brand in the UK. In 2024, a consortium led by KKR and including Singtel invested S$1.75 billion in the platform, and by 2026 KKR and Singtel had moved to acquire the remaining stake from ST Telemedia in a deal valuing the company near $10.9 billion. STT GDC is carrier-neutral, builds and operates campuses of multiple buildings in most of its major cities (e.g., a five-building campus in Pune, multi-building campuses in Chennai, Jakarta, and Ho Chi Minh City), and has increasingly focused new capacity on AI/cloud-ready, high-density design, including a newly opened 30MW facility in Seoul and a 45MW ‘AI-ready’ campus in Chennai.
