Experience in the UK

Slough 3 is part of five existing data centers we currently operate in Hemel Hempstead and Slough, six since the opening of London 1 in winter 2020. We have been in the UK market for over 20 years, originally operating as Gyron before being acquired by NTT and becoming part of the Global Data Centers division of NTT Ltd. in 2019.



Serving the London area

Our Slough 3 Data Center is located 20 miles west of central London in Berkshire. Slough is a prominent area for business in the UK due to its low rent costs but close proximity to London. The town's transport links also make it an attractive business location as it boasts good motorway connections and is located approximately 7 miles from London Heathrow Airport. Outside of London, Slough is the second largest data center cluster in the UK with 156,000 square metres of data center raised floor space.
