Google Cloud restored service in its London region on October 20 after a power event disrupted its infrastructure and banking services in Britain, according to Google and Reuters. The company's service dashboard marked the incident closed, recording a duration of seven hours and 52 minutes.
The disruption began at 06:08 UTC on Tuesday in the europe-west2 region, according to Google's status information. Its dashboard listed dozens of affected products, including database and application services. Reuters reported that websites and mobile apps used by banks, financial firms and public service providers experienced problems.
Revolut's status page showed that card payments and cash withdrawals were among services unavailable or partly unavailable during the incident, Reuters reported. A person familiar with the matter linked the bank's disruption to Google Cloud. Revolut said customers' money and data remained safe while its teams worked to restore services.
Lloyds, Halifax and HSBC also reported disruptions, according to Associated Press. Lloyds subsequently said its app was operational again and that it expected remaining services to return to normal following resolution of the underlying issues. AP reported that the effects extended beyond Britain to applications relying on London's infrastructure.
The impact also reached cloud software providers. ClickHouse Cloud's incident notice attributed degraded performance to Google's europe-west2 outage and identified zone B as affected. Its update said existing clusters should still accept reads and writes, but creation of new services was blocked until that zone became operational.
Google's closure notice provides a later recovery update than the initial reports of widespread failures. AP reported that Google planned to publish an incident analysis after its internal investigation. That review is expected to provide further detail about the event that interrupted the London infrastructure and the services depending on it.
