The cable landing stations are located within our highly secure data centre making us unique in the UK in terms of security resilience

Why Newcastle?

There are many reasons to choose Newcastle as your location of choice. Why continue to locate in congested London with increasing power costs and repeated issues with infrastructure when:

  • Stellium provides 80 MWs (designed to scale to 180 MWs) of REGO certified renewable power at Stellium Newcastle.
  • Our location in the North East is one of the lowest carbon intensity regions in the United Kingdom.

  • Stellium has no cooling issues – unlike London data centres who have experienced major cooling issues, Stellium have had none.
  • Stellium’s Tier 3+ data centre in Newcastle operates in less hostile temperatures than London, rarely exceeding 22 deg C v London’s 32 deg C (June 2023).The consequences are lower cooling bills and a cooling system that always works well within its design parameters.
  • Stellium provides metered power contracts – in London the infrastructure to give metered contracts is not always available. Energy is now 70% of your colocation cost so this is a major issue for your business in terms of transparency.
  • Stellium provides mobilisation time for contracts up to 1.3MW in 4 weeks.
  • Stellium has no latency congestion. In fact we provide some of the lowest latency now available in the UK. As the landing station for the latest international subsea fibre cables, Newcastle is now closer to New York than London is.
