The Sheffield Data Centre

Opened in June 2009, the Sheffield Data Centre is an N+1 Data Centre located in Holbrook, South Sheffield.

Located less than 8 miles outside Sheffield City Centre, and just over 5 miles from Junction 31 of the M1, the Sheffield Data Centre provides businesses of all sizes in Sheffield and South Yorkshire high quality, reasonably priced and professionally managed cloud servers, hosting, colocation, dedicated servers, and Data Centre services.

The Sheffield Data Centre is owned and run exclusively by High Availability Hosting Limited.

In mid-2012 we leased a second unit in the same business park, nicknamed the Sheffield Data Centre Extension (or DC1.5) it provides offices, meeting facilities, and room for a further 18 racks.

  • Our Blog contains pictures of the construction and fit-out, starting from April 2009.

Location

The Sheffield Data Centre is located in Holbrook, Sheffield.

Back in late 2008 / early 2009 as part of the initial planning phase, after consultations with Sheffield City Council, the Environment Agency and prospective clients, it was decided to locate the Data Centre out of the City Centre and Don Valley areas - away from the locations affected by the flooding in 2007, but still within the city limits.

The Environment Agency report on the location of the Sheffield Data Centre says the area is not at risk of "Flooding from rivers or sea without defences", and not at risk of "Extent of extreme flood".
