A sudden electrical disruption at a London data center triggered widespread outages across British financial institutions and digital platforms on Tuesday morning, leaving banking customers unable to access accounts, send funds or execute card transactions.
Google reported that an unexpected “power event” struck its europe-west2-b availability zone in the London region shortly after 6 a.m. UTC. The failure rippled across major consumer platforms that rely on the company’s infrastructure, taking down or crippling digital tools used by financial firms, delivery networks, web hosting providers and government services.
Cascading disruptions hit finance and consumer apps
Among the hardest hit were users of digital banking and money apps. Fintech platform Revolut confirmed that users encountered operational troubles during the morning, though the firm stressed that funds remained secure. “We can confirm that all our customers’ money and data are safe,” Revolut stated, apologizing for the inconvenience.
Traditional lenders experienced fallout as well. Halifax acknowledged digital service interruptions on social media platform X, stating that it was addressing issues affecting both its mobile application and online banking features. The Register reported that digital operations linked to Lloyds Bank and HSBC also suffered disruptions tied to the regional server trouble.
Personal finance tracking service Emma warned its users that operations were unavailable due to the London server failure, clarifying that the disruption was entirely technical rather than a cybersecurity breach. Frustrated consumers took to social media to report stranded travel plans, declined payment cards at airport terminals and difficulties reaching customer support desks.
Broad impact across public and private sectors
The technical fault extended well beyond personal finance. According to outage monitor Downdetector and company statements, parcel carrier DPD saw its website hindered, and web hosting firm SiteGround said its British data hub had been impaired by the incident. The Register reported that retail and utility platforms including Royal Mail, Rightmove, BT and Screwfix similarly experienced problems during the morning.
The breakdown reached the public sector as well. Britain’s courts and tribunal service acknowledged disruptions to cloud-supported video software deployed for remote courtroom hearings, stating that it was coordinating with technical providers to resolve the matter.
Internal systems affected within Google Cloud included several critical developer tools, such as Google Kubernetes Engine, App Engine, Cloud Run, Cloud Filestore and BigQuery Data Transfer Service, according to status logs reviewed by The Register.
Cloud concentration risks
The incident renewed scrutiny over corporate reliance on a handful of major cloud computing providers. Google, Microsoft and Amazon have aggressively courted enterprise and state clients worldwide, pitching high reliability alongside advanced artificial intelligence offerings.
Dr. Amro Al-Said Ahmad, a computer science lecturer at Keele University, told The Register that about 38 individual services were dragged down by the regional failure. Ahmad warned that core cloud zone failures quickly spread through digital supply chains to affect secondary applications and payment mechanisms, underscoring that firms must design resilient systems capable of withstanding regional disruptions.
Google indicated in status updates that engineers had mitigated the underlying electrical incident by midday and were prioritizing the restoration of active workloads. By 10 a.m. Eastern time, the company said service was largely restored, with only “a very small number” of accounts continuing to face residual difficulties.
