Equinix: How Interconnection Drives this Data Centre Giant

Equinix has been ranked No. 5 in Data Centre Magazine’s Top 100 Data Centre Companies list for 2025, recognised for its global interconnection platform, ongoing expansion in hyperscale markets and strategic approach to data centre energy infrastructure.

Building a global digital infrastructure

At its core Equinix operates data centres, which it brands as International Business Exchanges or IBX facilities and provides interconnection services that tie together cloud, network and enterprise ecosystems. Through its “Platform Equinix” model, it enables customers to co-locate their IT hardware in its facilities, while gaining direct access to networks, cloud onramps, partners and inter‑site connectivity. This is central to managed hybrid, multi‑cloud and edge strategies adopted by enterprises and cloud providers.

Equinix’s portfolio also includes its “xScale” division, which addresses hyperscale deployments. These are large, purpose‑built campuses designed for high power density and scalable growth. In Q1 2025 Equinix reported that it had 56 major projects underway in 33 metros across 24 countries, including 12 xScale projects, reflecting demand for larger footprints.

Its interconnection products continue to gain traction. In Q1 2025 Equinix noted a 7 % year‑on‑year rise in its interconnection revenue (9% in constant currency terms) driven in part by adoption of Fabric Cloud Router, a virtual routing service that allows customers to link multiple cloud and on‑premise environments via software‑defined paths.

In the Q2 2025 result release, the company said it added 6,200 net interconnections in the quarter, raising its total to over 492,000.

CEO Adaire Fox‑Martin of Equinix says: “Our diverse and carrier‑neutral ecosystems, rich interconnection capability and unparalleled global presence in key metros position us exceptionally well to deliver continued value to our customers.”

Scaling under pressure: financials and demand

Equinix’s latest financials show sustained expansion. In Q1 2025 it generated revenues of US$2.2bn, a 5 % increase over the same quarter last year (8 % on a normalised, constant currency basis, excluding power pass‑through). It also raised its full‑year guidance in mid‑2025, projecting revenues in the range US$9.23bn to US$9.33bn.

Executives point to AI, distributed workloads and cloud connectivity trends as drivers of demand. In Q2, closing 4,100 deals across more than 3,300 customers validated the company’s approach.

But demand has tested capacity. In its earnings commentary Adaire Fox‑Martin said: “It’s absolutely true that there are cases where we could not meet the contiguous capacity requirement of a customer in a tier-one metro. And if we had that capacity available, we could have met that demand for the customer.”

Equinix also works to strengthen its position in the co-location market. In mid‑2025 the company was named a Leader in the International Data Corporation MarketScape for Worldwide Datacenter Co-location Services, where its AI‑ready infrastructure, multicloud interconnection and global reach were singled out.

Powering growth: energy strategy and innovation

As data centres consume ever greater amounts of electricity – especially those supporting AI workloads – power strategy becomes a competitive lever. In August 2025 Equinix announced partnerships with advanced energy developers to reduce reliance on traditional utility supply and enhance resilience.

Equinix has committed to procure 500 MW of energy from Oklo’s next‑generation nuclear fission systems, pre‑ordered 20 microreactors from Radiant, and inked letters of intent in Europe with ULC‑Energy (using Rolls‑Royce small modular reactors) and with the molten salt reactor developer Stellaria.

Raouf Abdel, Executive Vice President of Global Operations, said: “Access to round-the-clock electricity is critical to support the infrastructure that powers everything from AI-driven drug discovery to cloud-based video streaming. As energy demand increases, we believe we have an opportunity and responsibility to support the development of reliable, sustainable, scalable energy infrastructure that can support our collective future.

"By working with our energy partners, we believe we can support the energy needs of our customers and communities around the world by helping to strengthen the grid and investing in new energy sources.”

Equinix has long used on‑site fuel cell systems. In collaboration with Bloom Energy, the firm is expanding solid‑oxide fuel cell deployment to over 100 MW across multiple sites, aiming to reduce emissions and water use.

Meanwhile, in markets like Spain Equinix is investing heavily in regional campus expansion. In mid‑2025 the company announced a €460m (US$530.5m) expansion of its Alcobendas campus in Madrid, reinforcing its interconnection footprint on the Iberian Peninsula. 

In India, Equinix opened a new AI‑ready facility in Chennai in September 2025. It begins with 800 cabinets, with plans to scale to 4,250 over four to six years, and includes liquid cooling to support high heat densities. Manoj Paul, Managing Director of Equinix India, said the facility will extend the company’s Mumbai ecosystem to southern India.

“We are delighted to announce the launch of our high-performance IBX data centre, CN1, in Chennai, marking Equinix's expansion in India and a pivotal step in advancing the nation's digitalisation journey," he said.

This year’s Top 100 number 5 ranking reflects how Equinix continues to expand its role in digital infrastructure by aligning interconnection, hyperscale growth and alternative energy strategy across its global platform.
