Located 35km northwest of London, the Hemel Hempstead 4 Data Center serves as a high-capacity hub within the Greater London Urban Area. The facility provides 4,800m² of dedicated server space designed to support complex IT and network infrastructures. Its strategic positioning offers direct connectivity to major carrier hubs in Slough and the London Docklands, enabling low-latency access and resilient enterprise networking.
The data center supports a total critical IT load of 12MW, engineered for high-density deployments. It operates on dual dedicated 11,000V high-voltage grid connections configured in a 2N architecture, backed by an on-site substation with a 60MVA capacity. A minimum N+1 UPS system with battery backup ensures seamless power continuity during primary supply interruptions.
As a carrier-neutral facility, Hemel Hempstead 4 offers a diverse range of connectivity options from global Tier 1 providers to regional carriers. Access is delivered through redundant Carrier-Meet-Me-Rooms (MMRs), enabling robust network redundancy, low-latency routing, and flexible interconnection for mission-critical workloads.
The facility utilizes a centrally managed cooling infrastructure integrated with the building management system (BMS). Data suites are maintained by precision room air conditioning units that regulate both temperature and humidity. The cooling architecture is designed with a minimum N+1 redundancy to ensure environmental stability during maintenance or equipment failure.
Security is implemented through a comprehensive, multi-layered model operating 24/7. The perimeter is fully fenced and monitored by internal and external IP CCTV systems. Access control includes proximity card authentication, biometric verification, and man-trap entry points. On-site security personnel continuously oversee all entry and operational zones.
The data center maintains multiple industry certifications, including ISO 27001, ISO 9001, ISO 14001, and PCI DSS compliance. Fire protection is provided through automated gas suppression systems within technical areas. Clients benefit from 24/7 on-site technical staff and Remote Hands services, ensuring immediate support for hardware management and operational requirements.
