NTT lists 12,800 m² of IT space in the first building (25,600 m² once fully built out) and 32 MW of critical IT load (64 MW once fully built out), with an average power density of 2.5 kW/m² and ancillary space on site. Power is supplied at 132 kV from two grid connections into an on-site 80 MVA substation with two 132/11 kV transformers in 2N. Two separate UPS systems (A and B supply) each have N+1 redundancy, with N+1 diesel generators for emergency power. Cooling is a redundant water-cooled system with N+1 free cooling and a compressorless design, using a cold air flooded room with suite cooling units and hot-aisle containment. Fire protection includes VESDA early smoke detection, water mist suppression and fire walls with at least 60 minutes of separation. London 1 is carrier- and cloud-neutral, with connectivity to LINX, carrier meet-me rooms, dark fibre infrastructure, redundant cabling and pre-cabling, and links to NTT's other London-area data centres. Security includes a 24/7 security operations centre and service control centre, palisade fencing, CCTV, ram-raid bollards to BS PAS 68:2013 and card-swipe entry and exit on all doors. NTT offers 24/7 remote hands, installation, client implementation, facility and audit support services. ### Services & suitable workloads - Colocation - Remote hands - Uptime service-level agreement: 99.999% power uptime availability (NTT service level agreement) - Total floor space: 137,778 sq ft NTT publishes an average power density of 2.5 kW/m² for London 1; rack and cage options are not listed. ### Technical specifications - Fire suppression: Water mist fire suppression with VESDA detection - Aisle containment: Hot aisle - IT space: 12,800 m² in first building; 25,600 m² at full build - Critical IT load: 32 MW; 64 MW at full build - Substation: On-site, 80 MVA; two 132/11 kV transformers (2N) - Grid supply: 132 kV from two grid connections - Average power density: 2.5 kW/m² - Fire separation: Fire walls, minimum 60 minutes ### Power infrastructure - Total facility capacity: 32 MW - Utility feeds: 132 kV supply from two grid connections into an on-site 80 MVA substation with two 132/11 kV transformers (2N). - UPS configuration: Two separate UPS systems (A and B supply), each N+1 - Generator backup: Yes ### Cooling systems - Cooling type: Water-cooled with free cooling; compressorless; cold air flooded room with suite cooling units - Cooling redundancy: N+1 - Aisle containment: Hot aisle NTT lists 32 MW of critical IT load (64 MW at full build), an 80 MVA on-site substation fed at 132 kV from two grid connections, A and B UPS systems each N+1, N+1 diesel generators and an average density of 2.5 kW/m². ### Sustainability NTT says London 1 uses free cooling and a compressorless cooling system designed for energy efficiency. - Carrier neutral: Yes - Exchange connections listed: 1 Carrier- and cloud-neutral, with connectivity to LINX, access to public, private and hybrid cloud providers, redundant carrier meet-me rooms, dark fibre infrastructure, redundant cabling, pre-cabling, high-performance internet access and inter-data-centre links to NTT's other London sites. ### Internet exchange connections #### LINX LON1 Unknown ### Network capabilities - Meet-me room: Yes - Dark fibre: Yes ### Physical security - Perimeter fencing - CCTV - Controlled access - Zonal access - Fire detection - Fire suppression ### Monitoring systems - 24/7 monitoring NTT lists a 24/7 security operations centre and service control centre, a multilevel security zone principle, palisade fencing, CCTV covering the perimeter, plant areas and data halls, ram-raid bollards to BS PAS 68:2013 and card-swipe entry and exit on all doors. ### Compliance overview ISO 9001, ISO/IEC 27001, ISO 22301, ISO 50001, ISO 45001, ISO 14001, PCI DSS, ISAE 3402 Type 2 and ISAE 3000 Type 2 reports (operator). ### Listed standards #### ISO 9001 - Scope details: Operator list; certificate scope not stated. #### ISO 27001 - Scope details: Operator list; certificate scope not stated. #### ISO 22301 - Scope details: Operator list; certificate scope not stated. #### ISO 50001 - Scope details: Operator list; certificate scope not stated. #### ISO 45001 - Scope details: Operator list; certificate scope not stated. #### ISO 14001 - Scope details: Operator list; certificate scope not stated. #### PCI DSS - Scope details: Operator list; certificate scope not stated.
