• London 1 Data Center

The London data center market is one of the most active colocation ecosystems in the world with a strong networking, internet, and cloud infrastructure presence. London is a strategic hub for data center services for both UK organizations as well as multinational companies who have established offices there and, from both a physical and digital perspective, require reliable services to reach local clients even faster. As the third-largest data center provider in the world, the Global Data Centers division of NTT, continues to build the foundation to successfully serve this vibrant data center market today and in the future. NTT is constructing one of the largest data centers in Europe in Dagenham, East London. Dagenham is located about 20 km east of London city center and 15 km away from the Docklands, which is established as the UK’s internet hub and serves as a backbone for the majority of the London Internet Exchange’s (LINX) infrastructure. Dagenham is also situated close to Shoreditch, which has recently become known as ‘East London Tech City’ or ‘the Silicon Roundabout,’ as many technology companies and start-ups have started to reside in the area.

The new campus "London 1 Data Center” is capable of up to 25,600 sqm of IT space and 64 MW IT load once fully developed. Phase one, with an initial 8 MW IT load, opened in December 2020, with three further phases planned to follow.

London 1 joins the five existing NTT-owned data centers. These data centers are located in the areas of Hemel Hempstead and Slough, respectively, both in the North-West region of London. With the addition of the Dagenham campus, we will be interconnected with these existing data centers, creating an impressive networked London operating platform and able to support over 100 MW of IT load. All our data center facilities serve traditional wholesale and retail colocation and hybrid IT solutions, supporting client market segments such as enterprise, hyperscale, SaaS, Telco, CDN and cloud.
