Experience in the UK

London 1 will join the five existing data centers we currently operate in Hemel Hempstead and Slough. We have been in the UK market for over 20 years, operating as Gyron before being acquired by NTT and becoming part of the Global Data Centers division of NTT Ltd. in 2019. London 1 Data Center opened in December 2020 is now available.


Serving the London area

Our London 1 Data Center is located in Dagenham, in east London and within easy reach of the Docklands, which is established as the UK’s internet hub and backbone for the global internet network that facilitates the majority of the London Internet Exchange's (LINX) infrastructure. Dagenham is also well situated for Shoreditch, which has recently become known as the ‘Silicon Roundabout,’ as many technology companies and start-ups reside in the area.
