Digital Realty Opens 6.4-MW Nairobi Data Center. Can Network Density Deliver Attractive Returns?

Digital Realty Trust recently opened a 6.4-megawatt data center in Nairobi, Kenya, known as NBO2, on September 7. This expansion builds upon the NBO1 data center and aligns with iColo's transition to Digital Realty Trust's brand in Kenya and Mozambique. The new campus offers more than just server space; it includes access to a community of over 100 networks, two internet exchanges, and a satellite teleport that connects terrestrial networks with satellite services.

Digital Realty Trust sees the potential in turning this network concentration into recurring customer relationships. Although the company did not disclose the development cost, pre-leasing, occupancy, or expected revenue, network density could provide a competitive advantage through interconnectedness, potentially luring additional customers and creating a network effect.

This advantage may lead to customer retention and recurring revenue, despite being an investment thesis rather than a proven outcome. The satellite link enhances the campus's reach to regions with limited terrestrial infrastructure, offering businesses an alternative way to serve regional users while maintaining selected data and applications in Kenya.

However, the leased capacity does not equate to revenue-producing capacity, as equipment installation, payment commencement, and commitment expansion remain uncertain. The undisclosed construction economics also play a crucial role in determining whether Digital Realty Trust can achieve strong occupancy without attractive returns, should development costs be high or if leases require substantial incentives.

Factors such as power reliability, cost, competition, and currency movements could impact the facility's profitability. While Digital Realty Trust identifies these risks, the opening announcement did not specify the lease currencies or power-cost recovery arrangements. With 73 hedge funds holding Digital Realty Trust at the end of 2Q2026, the company has bolstered its Nairobi offering with capacity near an established connectivity hub.

While the commercial logic is credible, quantifying the earnings contribution of NBO2 remains unconfirmed. The true test will be the leased capacity, customer commencements, interconnection revenue, and development returns, which will reveal whether NBO2 becomes more than a useful regional foothold.
