PMO-10792 Major incident affecting london datacentre

Start Date : 15/04/2026 09:57

End Date :

Impact : High - Serious / extended disruption

Risk : High - There is a high chance of Impact

Type : Emergency Maintenance

Status : Investigating


We have been notified of a major incident affecting our London datacentre. At 04:36 a leak detection alarm was received by the building management system - upon investigation engineers identified a significant water leak in the lower ground floor area, with water levels initially estimated at 30-40 centimeters. Emergency services were engaged and attended site to support mitigation efforts. The fire brigade isolated the water supply serving the affected area, and the standing water has slowly receded. Service Impact As the flooded area contains critical equipment: an 11,000 Volt transformer, Electrical switchboards, UPS systems, and generator controls, there is a high risk of losing cooling services and power to the building. Impact on some cooling equipment has been observed, contributing to elevated site temperatures, which remain stable, with the highest reading recorded at 31°C. Suspected root cause The suspected root cause of the water leak is a broken mains water or the fire mains system. Mitigation & Planned Actions Isolation kits are being installed, and access to the affected area remains restricted under the direction of Emergency Services. The fire brigade is on site, discharging water from the lower floor to support mitigation efforts, and water levels have since receded. The utility provider has been granted access to the building and is conducting checks on the substation. A pump team has been mobilized to the site with pumps and dehumidifiers. Approval has been received from the fire brigade to proceed with the use of pumps for water removal. Temporary cooling units are currently being deployed to the site. Site Team are working to bring in a temporary generator on site as a precaution to support environmental conditions at the site and are conducting manual temperature checks to verify readings against the Building Management System (BMS) and continue to closely monitor conditions while coordinating response efforts. Customers should prepare their business continuity plans in case conditions escalate.
