What City Lifeline does
City Lifeline operates a single 28,000 sqft carrier-neutral colocation data centre at 80 Clifton Street, Shoreditch, in the heart of London's Tech City. Established in 1993, the facility houses up to 600 racks and hosts Points of Presence from 24 carriers, providing low-latency connectivity across central London. The underlying infrastructure comprises DX cooling with cold aisle containment, N+1 dual diesel generator backup power rated to Tier 3 concurrent maintainability standards, 100% certified green electricity, and a 24-hour manned Network Operations Centre. The site is ISO 27001 certified by BSI.
The core product is colocation in shared data halls or private suites, sold on recurring monthly or annual contracts typically quoted on a per-rack, per-kW, and per-cross-connect basis. Adjacent revenue streams include managed IT services (managed networks, cloud computing, data backup, virtual data centre), connectivity services (dark fibre, cross-connects, IP transit, SIP trunking, DDoS mitigation), and direct interconnections to AWS and Azure that enable hybrid cloud architectures. The facility is differentiated primarily by location, carrier density, and tenure rather than by proprietary technology.
The customer base is heavily weighted toward UK and international telecommunications, voice, and internet service providers, including SingTel, Gamma Telecom, RedRaw Internet, iMarket Communications, and Pure IP, with secondary demand from Tech City start-ups and enterprises operating hybrid cloud estates. Go-to-market is direct enterprise field sales complemented by IP Expo presence and a content-led website, with no disclosed channel partner programme of meaningful scale. Since February 2016, City Lifeline has operated as a wholly owned subsidiary of Redcentric plc, a managed IT services group listed on the London Stock Exchange AIM market, and is also marketed as Redcentric's London Data Centre.
