When a banking app stops working, customers naturally worry about their money. On October 20, 2026, an incident affecting Google Cloud’s London region disrupted services used by several European banks. The following day, financial regulators began seeking more information about what happened and how the disruption was handled.
What happened to customers?
Reuters and Euronews reported problems with app access, payments and other services at institutions including Revolut, Lloyds and HSBC. Google linked the disruption to a power-related event at a third-party facility in its London network and later said services had been restored.
Revolut said customers’ money and data remained safe. That is an important statement from the bank, but it should not be represented as an independent audit of every system affected.
Why regulators are involved
European supervisors want to understand the incident and its consequences. Modern banking relies on shared technology platforms, so a failure in one cloud location may disrupt businesses that otherwise appear unrelated.
The outage also tests newer oversight regimes for providers deemed critical to the financial sector. Asking questions does not mean a fine or legal violation has already been established. Any regulatory finding would be a separate development.
What customers should do
During a service interruption, rely on official bank status channels. Be cautious about messages asking for passwords, account details or urgent verification, since criminals may exploit confusion even where there is no evidence of stolen funds.
With services restored, the central issue has shifted from recovery to resilience. Customers and regulators alike will want to know what safeguards can prevent a single infrastructure problem from affecting so many financial services again.
