## Incident Report ### **Summary** On Monday, 19 Oct 2026 (Tuesday, 20 Oct BST), a data center facility that hosts europe-west2-b, experienced an external electrical power disruption. This resulted in service unavailability for workloads located in this zone. As traffic was redirected to alternative cloud regions or unaffected zones within europe-west2 cloud region, these workloads experienced transient latency and elevated errors affecting services across europe-west2. The primary impact was mitigated after 6 hours 8 minutes. ### **Root Cause** **Facility architecture and background:** The data center facility in the UK region hosts Cloud clusters serving the europe-west2-b zone, which form part of the multi-zonal europe-west2 Cloud region. The site relies on a 2N utility power architecture—meaning the facility has complete duplicate power paths for every critical load—backed by a central high-voltage generator bank managed by a dual-redundant Programmable Logic Controller (PLC).
