The Cloudflare team suffered a significant service outage on June 12, 2025, affecting multiple critical services including Workers KV, WARP, Access, Gateway, Images, Stream, and others. The outage was caused by a failure in the underlying storage infrastructure used by Workers KV, which is a critical dependency for many Cloudflare products. The incident lasted for approximately 2 hours and 28 minutes, globally impacting all Cloudflare customers using affected services. The team had to rely on third-party cloud providers, which experienced an outage, directly impacting the availability of their KV service. As a result, various services such as Access, Gateway, WARP, and others were impacted, with some experiencing significant errors or failures. Despite being a failure on Cloudflare's part, the company acknowledged that the proximate cause was a third-party vendor failure. The outage did not result in data loss, but users experienced disruptions to various services including logins, authentication, and proxy functionality. The incident highlighted the importance of designing and building services with resilience in mind, as well as the need for careful dependency management. Cloudflare is taking steps to improve the resiliency of affected services, including accelerating existing planned work on improving Workers KV's redundancy and implementing new tooling to mitigate future incidents.
