A disruption at Google Cloud’s London infrastructure affected digital banking and several other essential services across the United Kingdom on October 20, 2026. Revolut, Lloyds Bank and HSBC were among the financial institutions reporting problems, leaving some customers unable to access services or complete transactions.
The outage highlighted how a technical failure at a major cloud provider can affect multiple businesses that depend on the same digital infrastructure.
Power Issue Triggers Disruption in London
Google attributed the incident to a “power event” affecting its europe-west2-b zone in London. The disruption began at approximately 6:08 a.m. GMT and affected services hosted in or dependent on the region.
Google said its engineering teams had restored service availability and that most customers were recovering. The company also said it would publish a detailed analysis after completing its internal investigation.
Revolut and Other Banks Report Service Problems
Revolut experienced disruption across several services, including card payments, money transfers, ATM withdrawals, currency exchange and stock trading. The company reassured customers that their money and data remained safe.
Lloyds Bank and HSBC also reported service difficulties. Lloyds said its app was operational again, while broader services were expected to return to normal after the underlying issue was resolved.
The incident showed how a cloud infrastructure problem can affect customers’ ability to carry out everyday financial activities, even when banks have not experienced a direct internal system failure.
Disruption Extends Beyond Banking
The impact was not limited to financial services. Reports also identified problems affecting services such as Royal Mail, delivery company DPD, property platform Rightmove, and parts of NHS England’s digital services. Some court proceedings were also disrupted.
The incident illustrated the interconnected nature of modern digital services, where organisations rely on external cloud platforms to run applications, websites and operational systems.
Cloud Concentration Raises Resilience Concerns
The outage has renewed questions about the risks of relying on a small number of major cloud providers. While cloud computing offers scalability and operational flexibility, a disruption in a shared infrastructure region can affect multiple organisations simultaneously.
UK regulators have already increased oversight of major cloud providers because of their importance to the financial sector. The Financial Conduct Authority said it was engaging with Google and affected firms to understand the incident’s impact.
For businesses, the event reinforces the importance of disaster recovery planning, resilient system architecture, clear customer communications and tested alternatives for critical services.
What Businesses Can Learn From the Outage
Organisations that depend on cloud infrastructure should assess whether critical workloads are concentrated in a single region or provider. Depending on their operational needs, measures such as multi-region deployment, backup systems, failover testing and incident response plans can help reduce the impact of future disruptions.
However, resilience measures must be carefully designed and regularly tested. Simply distributing workloads across cloud environments does not automatically guarantee uninterrupted service.
Conclusion
The Google Cloud outage on October 20 disrupted banking and other digital services across the UK, exposing the wider consequences of failures in shared technology infrastructure. Although services began recovering after the power-related incident, the event underlined the need for cloud providers and dependent organisations to strengthen operational resilience as more essential services move online.
