Millions of customers across the UK experienced severe disruptionA major system failure at Google Cloud’s London-based data center knocked out a wide range of essential digital services on Tuesday.
The outage, which Google blamed on a ‘power event’, crashed banking applications and payment platforms, leaving users unable to access funds, log into accounts or complete transactions at checkout.
Major financial institutions and platforms, including Revolut, Lloyds Bank, HSBC, Barclays, Bank of Scotland, NatWest, Halifax and Nationwide have reported widespread issues.
Delivery and postal services, including Royal Mail and DPD, in addition Remote video platforms used in courts across England and Wales were similarly affected, forcing judges to manage significant procedural delays.
Google has confirmed that while the initial power event has been resolved, services are experiencing downtime due to shared infrastructure dependencies. Google Cloud has indicated that a full recovery of existing workloads is expected to be provisionally completed by 2pm today (October 20, 2026).
The incident raised concerns about society’s heavy reliance on a handful of tech giants for fundamental digital infrastructure. Commenting on the widespread fallout, Sam Richardson, editor of How? money, said:
“Consumers will be rightly concerned about reports of widespread Google Cloud outages affecting a number of third-party businesses, including banks and payment platforms. In worst-case scenarios, these outages could prevent people from making essential purchases or even paying their bills.”
“Customers should keep evidence of affected payments in case they need to make a claim against their bank, and in the meantime, anyone who is likely to miss important bill payments should contact the company to ensure they cancel late fees.
“Technical and banking failures have become more common in recent years, and the impact can be widespread when they happen. It’s worth considering having back-ups in place in case your main provider goes down – for example, a card with another bank, and a small amount of emergency costs to tide you over if you can’t make card payments.”
While the disruption caused enormous practical difficulties for consumers, leaving many temporarily unable to buy groceries or pay for fuel, cybersecurity experts noted that the incident was a Availability failure rather than a security breach. Dr Hamza Mutaher, Lecturer in Cyber Security at Birmingham City University, noted:
“An outage does not alone mean that personal data has been stolen or compromised.
“The reported network failures point to an availability problem, rather than evidence of a data breach, although the full cause and implications still need to be established.
“This is the time for organizations to understand what technology and digital systems they depend on. This can be done through regular testing to see how essential services continue to function if a key provider is unavailable.”
As services slowly come back online after Google’s shutdown efforts, regulators and experts are urging organizations to review their emergency planning and recognize the hidden vulnerabilities of shared cloud infrastructures.
