Why is Telehouse a Top Global Data Centre Operator?

Telehouse has been named number 10 in the 2025 Top 100 Data Centre Companies ranking published by Data Centre Magazine. This placement reflects Telehouse’s global expansion, connectivity-rich network and new infrastructure investments across Europe, North America and Asia.

A global colocation and connectivity network

Telehouse traces its roots to London’s Docklands and New York metro areas in the late 1980s and has evolved into a global provider of carrier-neutral colocation, managed services and interconnection infrastructure. 

The company, part of Japan’s KDDI Corporation group, now operates across more than 45 data-centre sites in over 15 cities worldwide, serving carriers, cloud providers and enterprises. 

Central to its business is the provision of high-density data-centre space, connectivity to major internet exchanges and peering points, and access to cloud on-ramps linking infrastructure with the public cloud and other venues of compute. 

The breadth of its footprint and focus on interconnection position Telehouse as a key infrastructure partner for organisations shifting compute, storage or network loads globally.

Investment in infrastructure and sustainability

In October 2025 Telehouse announced the ground-breaking of its new London facility, “Telehouse West Two” at the Docklands campus, a £275m (US$370M) development with a capacity of 33MW and nine storeys totalling 32,000m², including 11,292m² of white-space across six levels. 

Kenkichi Honda, Managing Director of Telehouse Europe, said: “The new Telehouse West Two site marks another important step in our ongoing mission to deliver world-class, sustainable digital infrastructure.” 

The site is being designed with 100% renewable energy, air and liquid cooling systems, and HVO-fuel backup power systems, as part of its target to achieve BREEAM Excellent rating. This development reinforces Telehouse’s ability to support high-density workloads, including AI training and high-performance compute, while addressing sustainability imperatives. 

Meanwhile, in Canada, the company’s subsidiary, Telehouse Canada, has entered a strategic partnership with Vertical Data to accelerate AI infrastructure deployment across Canada, targeting enterprise GPU-based workloads. 

“Partnering with Vertical Data to bring their cutting-edge AI solutions to Canada is an exciting milestone for Telehouse Canada,” said Atsushi Kubo, President & CEO of Telehouse Canada.

Addressing AI, connectivity and colocation demand

Telehouse published its own research in the “AI Workload Strategies 2025” report, developed alongside S&P Global Market Intelligence and covering over 900 senior IT decision-makers globally. 

The report found that more than 90% of organisations view access to cloud on-ramps as critical to AI/ML architecture and over 40% of services across media, telecoms and utilities are placing AI workloads in colocation venues. Telehouse therefore positions itself to meet that trend by delivering facilities with direct connectivity, scalable power and high-density compute readiness. 

The company also won the Customer-Centric Service Excellence Award at the 2025 DCS Awards. 

Telehouse’s number 10 ranking in the 2025 Top 100 Data Centre Companies list reflects its global footprint, connectivity-centred model and forward investment in next-generation compute and sustainable infrastructure.
