The outage hit Google Compute Engine, Google Kubernetes Engine, Cloud Storage and Cloud SQL, according to the company's monitoring data. Revolut's official service status page listed 30 functions as partially unavailable, including cryptocurrency operations and business client services.

Complaints came from the United Kingdom, Germany, France, Malta, Lithuania, Latvia and the United States. In the UK, the number of reports exceeded 1,500 by morning, The Sun reported, citing DownDetector.

Revolut said customer money and data were safe. The company did not specify the cause of its link to the Google Cloud failure, Reuters reported. In September 2025, Revolut announced an expansion of its multi-year partnership with Google Cloud to run its global systems.

The disruption also affected third-party services that use Revolut's infrastructure. Payment operator GoPay reported problems processing card transactions for the bank. British monitoring system Tink, which provides access to bank accounts through Open Banking, reported that two types of operations via the Revolut integration were completely unavailable: retrieving account information and initiating payments.

Beyond Revolut, British personal finance management service Emma reported the same outage. The company directly linked the unavailability of its app to the Google Cloud failure in London. Other sectors were affected too: according to DownDetector, users reported failures at DHL in Germany, Booking.com in Italy and Spain, and the tax service website in the Netherlands.

In Germany, users of ING bank also complained of problems logging into the app. Late on Monday evening, customers of Dutch bank Rabobank encountered an inability to log in.

A month and a half before the incident, Revolut reported two data leaks. In September, the bank handed over data on some clients to attackers after mistaking a fake request from Italian government agencies for a genuine one. The company later reported another incident involving broker DriveWealth. There is no indication that the current technical failure is linked to a cyberattack.

Google initially offered no temporary technical fix, then recommended that customers move their projects to another zone or region.
