Google Cloud Outage Cripples UK Banks and Revolut, Exposing Infrastructure Fragility

What’s happening

A major power event in Google Cloud's London region triggered a widespread outage affecting UK banks and fintech platforms, with Revolut among the hardest hit. Google reported the incident has been mitigated, but service disruptions lasted hours.

Market impact

The outage exposed concentration risk in cloud infrastructure and raised questions about Google Cloud's redundancy and disaster recovery protocols. Financial services firms are now reassessing single-cloud dependencies, potentially accelerating multi-cloud strategies and benefiting AWS and Microsoft Azure.

Broader implications

Critical financial infrastructure's reliance on a handful of cloud providers creates systemic risk. Regulators may impose stricter uptime requirements and geographic redundancy mandates, increasing compliance costs for fintechs and banks.
