Ark Data Centres (UK): Alliance Park 2

Alliance Park 2 is part of the Alliance Park data centre campus operated by Ark Data Centres, located in W3 (Ealing / West London). As one of multiple modular buildings within the campus, Alliance Park 2 is designed to scale capacity alongside demand, leveraging Ark’s modular, low-carbon infrastructure approach. The campus’s location in west London offers excellent proximity to central London, major transport corridors, and a dense network of fibre and cloud providers. This positioning allows Alliance Park 2 to serve enterprises, cloud providers, and carriers seeking low-latency access and high-resiliency infrastructure just outside the city core.

⚙️ Facility Highlights

• Part of a modular, steel-centric campus architecture—Ark uses modular steel frames for flexibility, resource efficiency, and reuse. 
• Designed for Tier-3 resilience (expectation as part of Ark’s campus standard) 
• Low-carbon infrastructure with environmental optimizations (rainwater harvesting, efficient cooling) 
• Aiming for very low PUE (< 1.3) in design, supported by Ark’s cooling strategies (direct and indirect air cooling)
• Scalable power and compute capacity across the campus, with Alliance Park’s total compute capacity (across its buildings) cited at 50 MW across two data centres (campus-wide) 
• Cooling design combining direct air cooling and indirect air methods to optimize performance under varying ambient conditions 

🔐 Security & Compliance

• Multi-layered physical security throughout the campus (site perimeter controls, access zones) 
• Continuous monitoring via CCTV, access logging, and guard protocols (common in Ark’s data centres) 
• Compliance and operational standards: Ark holds certifications including ISO 14001, ISO 22301, ISO 27001, ISO 50001, ISO 9001, and Cyber Essentials Plus. 
• Resilience and reliability designed into the architecture (i.e., site redundancy, modular fault domain separation) 

🌐 Connectivity & Carrier Access

• Carrier-neutral architecture: customers can choose among multiple providers at the campus level 
• Direct cross-connects and interconnection services within the campus and to external networks 
• Close integration with Ark’s network ecosystem and connectivity to major London fibre and cloud hubs due to the campus’s strategic location 

💼 Who It Serves

• Cloud service providers and hyperscalers requiring scalable, low-latency infrastructure near London
• Enterprises and financial institutions needing resilient, modular colocation close to the city
• Carriers and network operators seeking interconnection points in western London
• AI, ML, or high-compute customers benefiting from Ark’s design toward high density and efficient cooling
• Organizations with sustainability and carbon-reduction goals, due to Ark’s emphasis on low-carbon design
