Google Cloud Outage Causes Widespread Disruption Across the UK

A major technology failure recently caused widespread disruption across the United Kingdom, affecting everything from banking apps to court systems. The outage, which occurred at a Google Cloud data centre in London, left millions of people unable to access essential digital services for several hours on Tuesday.

According to BBC News, the problem was caused by a "power event" within a specific part of Google’s infrastructure known as the "europe-west2-b" zone. Google Cloud provides the digital foundation for many businesses, allowing them to store data and run applications. When this infrastructure fails, the services built on top of it often stop working as well.

Financial services were among the most heavily impacted. Customers of major banks, including HSBC, Lloyds Bank, and the digital bank Revolut, reported being unable to log in to their accounts, make card payments, or withdraw cash. One Revolut user, Rachael Ellen, told BBC News that she was unable to pay for parking at a shopping centre because her account was not working. This left her in a difficult situation, as she could not access the money she needed at that moment. Both Revolut and Lloyds Bank later confirmed that their services were affected, but they assured customers that their money and personal data remained safe throughout the incident.

The impact extended beyond banking. The HM Courts and Tribunals Service reported that a video platform used for remote court hearings across England and Wales was knocked offline. The Guardian noted that this failure delayed several legal proceedings, particularly for defendants who were in custody and needed to attend court virtually. Additionally, some patients reported temporary glitches on the NHS app, and other services like Royal Mail and the property portal Rightmove also faced technical difficulties.

By Tuesday afternoon, Google reported that services were starting to return to normal. The company apologized for the inconvenience and promised to provide a full analysis of the incident on its service health dashboard. This dashboard is a website where Google shares updates about the status of its services worldwide. Despite the return to normal operations, the event has sparked a serious conversation about the UK's dependence on a small number of "hyperscalers"—a term used to describe massive companies like Google, Amazon, and Microsoft that provide cloud computing services to the entire world.

Experts argue that this reliance creates a dangerous situation. Michał "rysiek" Woźniak, an expert in internet infrastructure, told The Guardian that these companies have become "too big to not fail." He explained that because these firms are now so deeply connected to the daily lives of citizens and the operations of governments, it is very difficult for organizations to switch to other providers. Currently, it is estimated that up to 60% of the UK government’s digital infrastructure is hosted on services provided by these few large companies.

This outage is particularly significant because it is the first major test for UK regulators since they were given new powers to oversee these cloud providers. The Financial Conduct Authority (FCA) and the Bank of England have confirmed they are in contact with Google to understand exactly what went wrong. The Treasury committee of Members of Parliament (MPs) has also taken an interest in the matter. According to The Guardian, the committee chair, Meg Hillier, has asked for a report on how the regulators reacted and what the total impact was on the UK financial system.

As the digital world continues to grow, the physical infrastructure that supports it—such as data centres and power grids—remains vulnerable. While Google’s engineers worked quickly to resolve the issue, the event serves as a reminder of how fragile modern systems can be. As more of the economy moves into the cloud, the question of how to keep these vital services running without interruption remains a top priority for both businesses and the government.
