Revolut services are back online after yesterday’s outage.
The disruption began shortly after 7am BST on 20 Oct, when a power event hit Google Cloud’s London region (europe-west2-b). Failures interrupted services for hours. Most Google Cloud issues were mitigated by early afternoon; Revolut later confirmed the issue was fixed and services restored. Customer money and data remained safe throughout.
The impact was significant. Revolut has about 70m customers in Europe, and it seems most were affected. Reports came from the UK, Ireland, France, Spain and elsewhere. Card payments, transfers, ATMs, currency exchange and app access were affected. Revolut Business (850k+ companies) was also disrupted, hitting payments and operations.
Lloyds Banking Group, HSBC, Halifax, UK courts, Rightmove, DPD, and others also reported problems. Customers described abandoned purchases at tills and petrol stations, couldn't pay for travel, and businesses couldn't process payments.
This was a clear concentration-risk event. One cloud zone became a single point of failure for critical payment and banking services used by millions. The UK's FCA said it was engaging with Google and affected firms. The PRA and Bank of England were also reported to be in contact under the critical third-party regime (Google Cloud was designated in July 2026).
Revolut had previously signalled plans to move to multi-cloud by adding Amazon Web Services (AWS), with a roadmap to 2027. The outage indicates those measures were not yet sufficiently in place for core European operations. Some rivals, such as Monzo, were not widely reported as affected.
Google will investigate and publish a fuller report on the power event. That will clarify the technical details, but not the strategic questions: how quickly firms can reduce single-cloud and single-region dependence, and whether workable contingencies are actually ready. An event at one data centre near London was enough to disrupt millions of people and significant commercial activity.
