Stockley Park business estate

London II

Strategically located to the west of London within the thriving Prologis Park Heathrow, CyrusOne London II delivers 13.62 MW of IT load to 7,135 sq m (23,408 sq ft) of technical space across two floors. The facility is purpose-built, offering industry-leading energy efficiencies, the latest adiabatic free cooling technology, ultra-low PUEs, multilayer security, carrier neutrality and a Tier III+ level of resilience.

From initial design through to construction and ongoing operation, every aspect of the data center has been conceived and managed by our expert in-house team. We listen to understand customers’ requirements and directly translate them into clear designs. We work hard to build trusting relationships, and our technical ability, coupled with our straight-talking approach, allows us to build exactly what customers want.
