Premium UK data centres for a premium service

iomart has invested millions of pounds in building, equipping and operating eight UK data centres providing thousands of square metres of advanced data hall space in Glasgow, London, St Asaphs, Portsmouth, Nottingham, Leicester, Maidenhead and Manchester.

Each UK data centre is built using industry-leading infrastructure, is N+ in design and is safe, secure and staffed 24 x 7.

The benefit of this investment is clear – no legacy operations or practices – a clean sheet. This has enabled us to equip the facilities, and guarantee power supplies, to meet future computing demand and trends such as large scale virtualisation, distributed storage and multi site disaster recovery.

Our data centre is located within the heart of Europe’s centre of global finance – London’s Square Mile. The centre offers a combined net capacity of 1,520 m² (16,000 ft²) of high quality, resilient and secure space, across 4 separate data halls.

Great for Uk

A great host! They have their own datacenter, with good support for uk. For the rest of the world I cannot say, are they good. Seeing rank on mydc, speed is probably not so good.
