Google Restores London Cloud Services After Major Outage Disrupts UK Businesses

Google has restored most services in its London-based cloud computing region after a significant outage disrupted businesses and public services across the United Kingdom on Tuesday, October 20, 2026. The disruption affected Google’s europe-west2 region, which supports a wide range of online applications and digital infrastructure. According to the company, a power-related incident caused elevated error rates and intermittent network failures across multiple services. Google said its engineering teams worked to restore operations and prioritised the recovery of existing workloads. By the afternoon, the company reported that services had recovered for most customers, although a small number continued to experience problems. Google apologised to affected customers and said it would provide a more detailed explanation after completing its investigation.

Several major financial institutions experienced disruption during the incident. Digital bank Revolut reported problems affecting multiple services, including card payments and ATM withdrawals, while Lloyds Bank and HSBC also reported difficulties with some customer services. Revolut reassured customers that their money and personal data remained safe despite the interruption. Halifax was among the other financial institutions affected, highlighting how cloud infrastructure supports essential banking operations behind the scenes. For customers, the outage meant that certain transactions and digital services were temporarily unavailable or unreliable. The incident demonstrated how a technical problem at a cloud provider can quickly affect everyday financial activities, even when the banks themselves have not suffered a direct security breach.

The disruption extended beyond banking into other areas of the British economy. Royal Mail, delivery company DPD, property website Rightmove and telecommunications provider BT were among the organisations reporting service problems. Britain’s court system also experienced difficulties with its Cloud Video Platform, which supports remote hearings. Several Google Cloud products were affected, including services used for computing, data processing, storage and application hosting. The incident originated in the London cloud region’s europe-west2-b availability zone. Although cloud systems are designed to provide resilience through multiple facilities and zones, the outage showed that failures in one part of the infrastructure can still affect customers whose applications depend on that location or have not been configured to switch automatically to alternative systems.

The outage has renewed concerns about the growing dependence of businesses and public institutions on a small number of technology companies. Cloud providers such as Google, Amazon and Microsoft operate infrastructure that supports banking, healthcare, government services, retail platforms and thousands of other organisations. Moving applications to the cloud can improve flexibility and reduce the need for companies to maintain their own data centres, but it can also create concentration risks when many essential services depend on the same provider or region. The incident has also drawn attention to the importance of disaster recovery planning, backup systems and multi-region infrastructure. Organisations that need uninterrupted services may have to invest in systems that can continue operating when a cloud region experiences a serious technical failure.

Regulators are also examining the implications of such disruptions for financial stability and consumer protection. The UK’s Financial Conduct Authority has been assessing the impact on affected firms, while the incident comes amid stronger regulatory oversight of major cloud providers that support critical services. European authorities have similarly identified important technology providers whose failures could affect financial institutions across the region. Google has said it will publish a fuller incident report after its investigation, which should provide further information about the power event and the measures taken to restore service. Although most affected workloads had recovered by Tuesday afternoon, the incident is likely to prompt businesses to reassess their contingency arrangements. Ultimately, the event highlights a central challenge of the digital economy: as more essential services depend on cloud computing, maintaining reliable backup systems and reducing single points of failure become increasingly important.
