About The Data Centre

Volta Great Sutton Street data centre is a cloud and carrier-neutral hub in central London. Located in the heart of the UK’s internet infrastructure, Volta GSS is undoubtedly the most connected, powerful and resilient home for businesses' cloud and IT infrastructure needs.

In addition to being highly resilient and a concurrently maintainable Tier III data centre, Volta’s Colocation London provides the ‘4Cs' of diamond quality to fully support the demand of 100% uptime – Convenience, Connectivity, Capability and Customer service. Locating at Volta GSS expands a company’s global reach, offering secure and direct access to local communities, world markets and everything the Internet has to offer, all within a central London location.

Volta GSS’s large capacity in power and space, as well as innovative technologies, help businesses achieve an essential scalability, flexibility and resilience in IT delivery satisfying today’s and tomorrow’s requirements - from the ability to locate high density computing racks alongside low density networking racks enabled by advanced row-based cooling, to two direct power feeds on separate redundant grid rings, and to UK’s first ever ‘Power-by-the-Hour’ service, a disruptive pricing model initiative on power consumption.

As companies grow increasingly allied to technology, any downtime your equipment suffers can prove detrimental to business. Housing your IT infrastructure within central London enables important maintenance work to be rapidly carried out without the inconvenience of travelling to the M25 or beyond.
