As well as accelerating your business strategy by freeing up office space and resources, our colocation solution delivers the following benefits:

An cost-effective, environmentally friendly solution

We chose Ark as our data centre partner because they offer world leading PUE and eco‐friendly cooling, in partnership with BladeRoom, ensuring your data centre infrastructure meets your environmental goals and reduces energy costs, with zero compromise in performance. Ark’s data centres are the most environmentally efficient in the UK, saving customers on average around £1.1 million per megawatt and 6,000 tonnes of taxable carbon on an annual basis.

Availability and resilience

Our colocation solution is hosted within Ark’s purpose built, highly resilient Tier III data centres, on UK sovereign territory, separated by >50 miles for geographical diversity. We tailor our support services and SLAs to meet your business needs and can provide a dedicated team or shared resources to suit your budget, goals, and requirements.

Robust security and compliance

Ark’s data centres are the UK Government’s data centre of choice and are accredited to UK OFFICIAL classification as standard. Ark is the only data centre operator with pan-government accredited facilities at all levels of security, in line with CPNI guidance, and assured by NCSC, underpinned by our comprehensive SLAs. Our on-site data centre engineers are SC cleared and above, ensuring your data is in safe hands, 24 / 7.

A smooth, secure migration process

We have extensive experience of large‐scale, secure data centre migration projects, and draw on this throughout each phase of the migration process, working in partnership with several leading server relocation companies to ensure the seamless, secure transition of IT infrastructure to new premises. Furthermore, as Ark’s data centres are already pan‐government accredited, you will enjoy complete peace of mind that even the most stringent compliance requirements will be met.
