Millions of Revolut customers were affected, and other banks including Lloyds, HSBC and ING Germany reported problems at the same time.

What's the connection? Reporting has not established that the cloud fault caused Revolut's outage. But Revolut uses Google Cloud, and a person familiar with the matter told Reuters that Revolut's disruption was linked to the Google Cloud incident.

Why it matters: Even if the link is confirmed, the episode shows the cloud-concentration risk facing financial firms: one provider's regional fault can coincide with disruption across unrelated services.
