A major Google Cloud outage hit the United Kingdom on Tuesday, October 20, following a significant "power event" at the company's London data center region. The disruption began at approximately 07:00 BST at Google's Europe-west2 facility, which serves as its primary cloud region for the UK.
This incident highlights the vulnerability of modern digital infrastructure to localized power failures. In an official update, Google confirmed "an issue with multiple services," stating, "due to a power event, we have suffered an outage within the Europe-west2 zone.
The power event is mitigated." While the company successfully addressed the immediate power failure, the underlying technical cause remains under investigation. Google promised that partial mitigation would follow within 30 minutes of the initial report.
Among the most severely affected entities was the digital bank Revolut, which manages over 80 million customers globally. Thousands of users reported being unable to process payments, access their funds, or contact customer support services.
The sudden inability to manage finances caused widespread frustration among the bank's user base during the morning hours. Revolut issued a statement reassuring its clients that "all customers' money and data are safe" and confirmed that their technical teams had been working to resolve the connectivity issues since they were first identified.
Other major financial institutions, including Halifax and Lloyds, also reported intermittent problems with certain online banking services during the same window. The impact of the outage extended far beyond the financial sector.
The HM Courts and Tribunals Service reported that its Cloud Video Platform, which is essential for conducting remote legal hearings, was severely disrupted. Consequently, the Criminal Bar Association issued a warning that barristers across England and Wales were unable to proceed with scheduled trials and other legal hearings.
Public services and entertainment sectors were not spared from the disruption. The Royal Mail reported logistical challenges, and the Hitchin Town Football Club confirmed that its digital ticketing system had been rendered inaccessible due to the cloud failure.
These reports underscore the heavy reliance of diverse industries on centralized cloud infrastructure. In its latest communication, Google reiterated that the "power event" had been mitigated.
The company added, "partial mitigation to infrastructure services will be observed within the next 30 minutes, and the remaining services will be mitigated thereafter." Engineers worked throughout the day to ensure full restoration of all affected cloud-based applications. Industry experts noted that while cloud providers typically maintain redundant systems, localized power events at data centers can still cause significant cascading failures.
This incident serves as a reminder for businesses to maintain robust contingency plans for when major cloud service providers experience downtime. As of late Tuesday, most services began showing signs of recovery.
Google has promised a full post-mortem report to provide transparency regarding the specific nature of the power event and the steps taken to prevent future occurrences of such widespread outages. The incident remains a focal point for discussions regarding digital resilience in the UK.
As businesses continue to migrate their operations to the cloud, the demand for higher uptime guarantees and more resilient power infrastructure for data centers continues to grow.
