With operations spanning Mumbai, Delhi-NCR, Pune, Bengaluru, Hyderabad, and Chennai, Iron Mountain delivers the pan-Indian footprint and consistent global standards needed to support distributed AI workloads, cloud deployments, and hyperscale infrastructure across India's fastest-growing technology markets.
MUM-1, our data center in Mumbai, is one of India's busiest and most successful data centers, operational since 2015 with a thriving customer ecosystem representing the densest interconnection environment in the country. The facility provides on-site access to nine leading carriers, over 200 ISPs, and four major Internet Exchanges (DE-CIX, AMS-IX, Extreme IX, and NIXI)—more exchange connectivity than any other Mumbai facility. All major cloud providers maintain a direct presence, including AWS, Azure, Google Cloud, and Oracle, enabling low latency to hyperscale infrastructure. MUM-1's strategic Navi Mumbai location provides direct access to international submarine cable landing stations, where most of India's 17 major subsea connections terminate. The facility operates on Iron Mountain's 5.5-acre campus alongside MUM-2 and in proximity to the planned MUM-3, providing seamless expansion capacity as customer requirements grow.
MUM-1's 700+ customer ecosystem creates immediate interconnection opportunities. The facility houses nine leading tier 1 carriers on-site, eliminating the need for expensive off-net cross connects and providing competitive pricing through carrier diversity. Four major Internet Exchanges—DE-CIX, AMS-IX, Extreme IX, and NIXI—enable direct peering with hundreds of networks. All major cloud providers maintain on-site infrastructure with direct cloud on-ramps to AWS, Azure, Google Cloud, and Oracle, delivering low latency and avoiding long-haul bandwidth charges. Over 200 ISPs provide domestic and international connectivity options optimized for different workload requirements.
For Mumbai colocation, Iron Mountain also operates MUM-2 in Navi Mumbai, a 110,631-square-feet, purpose-built facility with 6.3 MW of IT load, designed for high-density AI workloads. MUM-2 opened in 2023 with 1,072-rack capacity across 4 data halls, featuring N+1 DG sets, chilled-water-based cooling in N+2 configuration, and express feeder connectivity. MUM-3, scheduled for opening in Q1 2028, will add 85MW of hyperscale-ready capacity campus-wide, bringing Iron Mountain's total Mumbai campus to 93 MW across multiple interconnected facilities in Navi Mumbai. Across India, we operate NCR-1 in Noida (12 MW potential), PUN-1 in Pune (1.6 MW), BLR-1 in Bengaluru (4.1 MW), and HYD-1 in Hyderabad (5.7 MW). Chennai will add CHN-1 and CHN-2, totaling 48 MW, on a 4.3-acre campus in Ambattur. Explore our data centers in India here.
MUM-1 delivers 2.5 MW of power capacity across 50,000 square feet (4,645 square meters) of data center space with 444-rack capacity across 3 server halls and floor loading capacity of 1,500 kg/m², built to Uptime Tier III standards. The facility is located on Iron Mountain's 5.5-acre (2.2-hectare) campus in Navi Mumbai, with excellent transport links and diverse power supplies. The Mumbai colocation facility supports multiple deployment options, including colocation cabinets for distributed workloads in quarter-rack increments, dedicated cages for department-level deployments ranging from 1 to 10+ racks, and custom suites for mission-critical applications requiring isolated infrastructure.
MUM-1 implements six physical security layers engineered to protect customer infrastructure and data. Perimeter security begins with 24/7/365 manned security at campus entry points, with vehicle inspection protocols and visitor management systems. Multi-factor authentication controls facility access via card readers and biometric scanners, with strict protocols that limit entry to authorized personnel. The data center floor requires additional authentication beyond building access, creating segregated security zones. Comprehensive video surveillance covers all access points, data halls, and common areas, with recordings archived in accordance with compliance requirements. Equipment cages feature locking mechanisms with customer-controlled access, and custom suites can implement additional security layers based on specific requirements. 24/7/365 on-site security personnel provide continuous monitoring and rapid response to any security events.
Yes, MUM-1, our Mumbai colocation facility, is specifically designed to support organizations at every stage of growth, from startups deploying their first infrastructure to enterprises operating thousands of servers. For server colocation, cabinet options are available in quarter-rack increments (fractional server colocation), allowing businesses to start with just 10U of space and scale as requirements grow. This "grow-as-you-go" approach eliminates the need to overprovision infrastructure, reducing capital expenditure while maintaining the flexibility to scale rapidly as demand grows. Smart Hands services enable remote infrastructure management, eliminating the need for on-site staff in the early stages of business growth. As organizations scale, MUM-1 colocation provides seamless expansion pathways from cabinets to cages to custom suites, with the option to expand onto MUM-2 or MUM-3 within the same campus while maintaining unified operations. This flexibility makes MUM-1 ideal for Indian startups scaling domestically, international companies entering the Indian market, or enterprises testing new applications before committing to larger deployments.
