Ark Data Centres (UK): Spring Park P3

The Ark: Spring Park P3 Data Center is part of the Spring Park campus in Corsham, Wiltshire, UK — a high-security, multi-building digital infrastructure campus operated by Ark Data Centres.

Spring Park is one of Ark’s flagship facilities, designed to support high-density, scalable workloads within a campus environment featuring multiple buildings (P1, P2, P3, SQ17, and expansion sites P4 / P5). Strategically, the P3 facility benefits from shared campus infrastructure (power, connectivity, security) and proximity to a dense fiber ecosystem. The Spring Park campus is engineered for modular growth, integrating sustainability, flexible deployment, and high-availability operations across its multiple data halls. 

⚙️ Facility Highlights

• Built / year: 2022 (P3 building) 
• Campus total compute / infrastructure capacity: 55 MW (across all Spring Park buildings) 
• Modular architecture enabling scalable deployment across P1–P5 and SQ17 buildings 
• Data halls with support for high-density loads (exact per-rack power not published) 
• Cooling technologies: direct air-cooling, indirect air techniques, and liquid-cooled options, designed for energy efficiency and low PUE performance 
• Campus-wide fiber and network infrastructure: 16 diverse fiber providers serving the campus 
• Rack / capacity scale: Spring Park campus supports between 10,000 to 13,000 rack positions across its buildings 
• Campus size: 38 acres dedicated to secure data center operations 

🔐 Security & Compliance

• High-security campus: fenced perimeter, controlled access, multi-layered security across all facilities 
• 24/7 CCTV surveillance across building entrances, colocation suites, and campus zones (multiple shared MMR spaces) 
• Access and room segregation: multiple private Main Meet Me Rooms (MMRs) and shared MMRs enabling secure internal connectivity separation 
• Strong carrier and fiber diversity ensures path redundancy and resilience against single-fiber failures 

Note: I did not find any publicly published ISO, Tier, or compliance certifications specifically for P3.

🌐 Connectivity & Carrier Access

• Carrier-neutral campus with broad choice among fiber providers — 16 diverse providers across Spring Park 
• Multiple fiber entry paths, private and shared MMRs, resilient connectivity architecture 
• Dense interconnection opportunities within the Spring Park campus (cross-campus links) and external fiber ecosystems
• Integration of cloud, network, and colocation services via on-site infrastructure 

💼 Who It Serves

• Enterprises and hyperscalers requiring high-capacity, modular colocation in the UK
• Network operators, carriers, and content providers needing dense fiber interconnections
• Cloud and SaaS providers seeking infrastructure in a campus with shared campus services
• Workloads with high compute and cooling demands (AI, HPC, data analytics) due to advanced cooling capabilities
• Organizations requiring flexibility in footprint and deployment across a campus environment
