Google Cloud outage disrupts UK banking and NHS services
A power failure at a Google Cloud datacenter in London caused cascading disruptions across the UK, affecting major banks, Royal Mail, and the NHS app. The incident, peaking around 9am, highlighted Europe's heavy reliance on a few cloud providers. Unlike last year's massive AWS outage, this event was largely confined to the UK, though it underscored the fragility of critical infrastructure dependent on single-vendor zones.
Key points
- A power outage at Google's europe-west2-b zone in London triggered service failures for Royal Mail, Revolut, HSBC, and Lloyds Bank.
- The disruption, which peaked around 9am, also caused temporary glitches in the NHS app and paused court hearings.
- Revolut confirmed a service disruption but assured customers that their money and data remained safe.
- The incident is smaller in scale than the 15-hour Amazon Web Services outage in Virginia last year, which affected global services like Roblox and Signal.
- The event highlights the UK's and Europe's structural reliance on a limited number of cloud providers for critical business operations.
- Most issues were resolved by mid-afternoon, according to Downdetector reports, with impacts largely confined to UK-based businesses.
A power failure at a Google Cloud datacenter in London has caused significant disruptions to key UK services, exposing the continent's dependence on a small number of cloud infrastructure providers. The outage, centered in Google's europe-west2-b zone, led to cascading failures that affected major financial institutions including HSBC, Lloyds Bank, and Revolut, as well as Royal Mail and the National Health Service (NHS) app. Court hearings were also delayed due to the technical glitches.
According to Downdetector, the issues peaked around 9am and were largely resolved by mid-afternoon. Revolut confirmed a service disruption affecting multiple platforms but noted that customer data and funds remained secure. While the impact was widespread, it was mostly confined to UK-based operations, distinguishing it from the massive Amazon Web Services outage in Virginia last year. That previous incident, which lasted nearly 15 hours, affected global services such as Roblox and Signal, demonstrating the far-reaching potential of such failures.
The incident has reignited debate about the resilience of critical infrastructure. With Google maintaining more than a dozen zones in Europe, the concentration of data and operations in specific locations creates single points of failure. As businesses continue to migrate to cloud platforms, the reliability of these providers becomes a critical factor for economic stability and public service delivery.
