Cloudflare outage, 12 June 2025

Cloudflare Workers KV outage (third-party storage failure) (12 June 2025). The disruption lasted about 2 hours 36 minutes, according to Cloudflare’s own timeline. It began at 17:52 UTC and was resolved at 20:28 UTC. Part of the storage infrastructure behind Cloudflare’s Workers KV is backed by a third-party cloud provider, which had an outage.

What happened next. About 90% of KV requests failed, and because many Cloudflare products rely on KV for configuration and identity, they failed too.

What changes. Cloudflare is removing KV’s dependency on any single storage provider and building tooling to progressively re-enable namespaces during recovery.
