A major power outage at a Google Cloud data center located near London has triggered widespread technical disruptions across the United Kingdom, heavily impacting major financial institutions and online services.

According to US technology giant Google, the incident stemmed from an unexpected “power event” that began early Tuesday morning within its designated europe-west2 cloud region, resulting in elevated error rates and intermittent network failures for multiple cloud-hosted applications.

The technological glitch had an immediate ripple effect across the UK’s financial sector, with digital bank Revolut reporting severe problems with essential user features such as mobile app transfers, ATM cash withdrawals, and card top-ups. Traditional financial powerhouses, including Lloyds Bank and HSBC, also confirmed that customers were experiencing significant difficulties accessing online banking applications and digital platforms.

Beyond the banking sector, internet service tracking monitors and public reports highlighted service disruptions across other prominent digital platforms, including the property portal Rightmove and aspects of the Royal Mail postal service network.

Google engineers and technical support teams mobilized swiftly to isolate the fault and restore full operational capacity, with tech representatives projecting a gradual return to normal services by early afternoon.

Representatives for affected financial institutions, including Revolut, issued public apologies for the temporary inconvenience while reassuring anxious customers that all user funds and personal data remained entirely secure throughout the incident. The unexpected outage underscores the fragile reliance of modern global financial infrastructure on centralized cloud-computing data centers.
