Google Cloud London outage shows need for tested enterprise resilience
A power disruption in Google Cloud’s London region affected numerous services, including banks, delivery platforms, NHS app functions, and court video links. The article argues that hyperscaler reliability features are only building blocks and that organizations must plan, pay for, exercise, and take responsibility for their own continuity measures. Enterprises should not treat a cloud provider’s capabilities as a complete resilience strategy.
Google linked the London disruption to an early-day power problem in its europe-west2 data centers. The effects reached beyond direct customers, hitting banks, delivery and e-bike services, budgeting tools, NHS app appointment functions, and court video links. In a later update, Google said most disrupted workloads were back in service, while a small customer set remained impacted.
The incident highlighted shared dependencies: unrelated-looking services may depend on the same regional infrastructure, provider-run services, connectivity, authentication, interfaces, and operational workflows. That interconnection can widen the impact of one cloud-region failure.
The outage could affect public trust in digital-first services, especially for patients relying on NHS app appointments, court users needing video links, and customers of banks or delivery platforms. Even brief failures may cause delays, confusion, or lost transactions, and could push organizations to invest more in tested continuity plans. The wider lesson may be that society’s dependence on shared cloud infrastructure makes resilience a public-facing concern, not just an IT issue.
