STT Mumbai 3 sits inside the Bandra Kurla Complex, Mumbai's purpose-built financial district, which the operator describes as making this the only enterprise-grade data center located within the city's BFSI hub. Operational since 2009, it is the largest of STT GDC's three legacy Mumbai buildings by both power and floor space, with 9 MW of IT load across roughly 16,700 square meters of gross floor area, well ahead of the older Prabhadevi and Andheri sites. The facility carries the same ISO management-system stack as its sister buildings — ISO 27001, ISO 20000-1, ISO 45001, ISO 14001 and TL 9000 — and the operator's own website additionally claims CEEDA energy-efficiency certification, though that specific credential is not listed in the facility's published factsheet, so it should be treated as an unverified claim rather than a confirmed certification. Positioned for banking, financial services and insurance tenants that need to be physically close to Mumbai's financial center, STT Mumbai 3 anchors the operator's original India footprint alongside its newer Navi Mumbai, Palava and Pune campuses.
