Digital Realty London City (Hanbury Street) Data Centre
Located on a site on Hanbury Street, the Digital Realty London City campus - comprising the LON1, LON2, and LON3 facilities - is a significant digital infrastructure hub in East London. The facility was formerly known as Interxion before its acquisition by Digital Realty.
Infrastructure and Power
The data centre campus is designed to provide high levels of reliability and service continuity. Across the site, the facility operates with a total power capacity of 16.0 MW to support large-scale IT requirements.
To prevent service interruptions, the facility uses a 2N uninterruptible power supply (UPS) system. In the event of a mains power failure, N+1 standby generators are ready - supported by fuel stored on-site. The cooling systems utilise an N+1 redundancy configuration to maintain optimal operating temperatures for hardware, employing chilled water and efficient airflow management.
Security and Standards
Physical security is maintained 24 hours a day by on-site personnel. The facility is monitored by 24/7 CCTV surveillance with long-term recording retention. Access to the data halls requires multi-layered authentication - including biometric scanners and card readers - alongside anti-tailgate systems.
The facility meets several international standards for management and security:
-
ISO 27001 for information security.
-
ISO 9001 for quality management.
-
ISO 22301 for business continuity.
-
PCI DSS compliant for the physical security of payment card data.
-
SOC 2 and SOC 3 certified for service organisation controls.
Environmental Sustainability
The London City campus is powered by 100% renewable energy and is certified to the ISO 50001 standard for energy management. This certification ensures that the site follows a systematic approach to achieving continual improvement in energy performance and efficiency.
The facility is also certified to ISO 14001 for environmental management. Efficiency at this facility is usually achieved by utilising modern efficient UPS systems and advanced cooling controls to minimise energy waste.
Connectivity and Network Access
The facility is a long-established primary connectivity inter-connect point for network traffic in the United Kingdom. Its location close to the City of London financial centre has made it a favoured choice for financial services and trading companies due to close low-latency connectivity.
The campus houses core nodes for major internet exchanges - including LINX and LONAP. The site provides access to over 195 different telecommunications carriers, including Tier-1 networks and connectivity on diversely routed fibre paths.
