Google Cloud Power Event Disrupts London Region, Exposing Single-Region Resilience Gaps

Summary
Google said a power event hit London data centers in its europe-west2 region, disrupting cloud services early in the day before recovering most affected workloads.
Banks, delivery firms, e-bike providers, budgeting apps, some NHS appointment services and court video-link systems were caught because many shared the same regional cloud and service dependencies.
The outage underscored that hyperscaler tools—multiple zones, replication, backups and failover options—are only building blocks if enterprises still run critical applications through a single region, database or identity path.
Google’s incident also highlighted hidden dependency chains across APIs, managed services, DNS, monitoring and third-party platforms, where one regional failure can cascade far beyond a single customer.
The broader lesson is that resilience must be designed and tested workload by workload, with explicit spending on multiregion architecture, backup restores and failover drills rather than assuming cloud migration alone removes single points of failure.
