Just one hundred miles from London’s urban density and located in the U.K.’s tech corridor, our 46-acre Cardiff campus will include three data centers once fully developed, two of which are now operational. The campus, designed and built to exceed Tier III standards, will feature 2,000,000 gross square feet (186,000 gross square meters) with density per rack ranging from 2kW to 125kW+. CWL1 is considered to be one of Europe’s largest data center campuses to meet customer demand from around the world.

Sited near the M4 and major airports, the campus is easily accessible by air, rail and car—about 40 minutes from Bristol. The secure site meets the U.K. government’s highest standards and is just one of the many reasons that multiple blue-chip, high-growth companies currently house their IT infrastructure in one of the U.K.’s most efficient data centers.

We’re pleased to offer you all the advantages that come with choosing Vantage Data Centers. You’ll find a unique combination of people and technology: cooling and power that’s both sustainable and reliable; flexible room design and rigidly enforced physical security; and amenities that keep your staff happy—all backed by operational excellence at every location as we scrupulously adhere to our rigorous service and delivery standards across the globe.

Rich in connectivity, the Cardiff campus has fiber delivered by many Tier 1 service providers and offers low latency between Wales and London of less than 1.5 milliseconds. Currently, building one has three points-of-entry (POE) and eight Meet-Me-Rooms (MMR), with the ability to expand. Buildings two and three will have similar connectivity, all based on customer requirements.

The campus offers Cloud Gateway, which facilitates direct access into leading public cloud providers such as Microsoft ExpressRoute.

Ten-ton, anti-ram raid blocks are installed between paved areas and entries for added protection. Traffic management systems are in place at the entrance and the exit, supported by double airlock gates. Layered access is controlled using zoned card swipe and CCTV monitoring throughout and can be supplemented with custom fitments for multi-factor authentication, secure trunking, airlocks and additional surveillance.
