Unauthorized TLS certificates were issued for 1.1.1.1 by a Certification Authority without permission from Cloudflare. These rogue certificates have now been revoked. Read our blog to see how this could affect you.

On July 14th, 2025, Cloudflare made a change to our service topologies that caused an outage for 1.1.1.1 on the edge, resulting in downtime for 62 minutes for customers using the 1.1.1.1 public DNS Resolver as well as intermittent degradation of service for Gateway DNS.

We’re deeply sorry for this outage.

This outage was the result of an internal configuration error and not the result of an attack or a BGP hijack. In this blog post, we’re going to talk about what the failure was, why it occurred, and what we’re doing to make sure this doesn’t happen again.

Multiple Cloudflare services, including Workers KV, Access, WARP and the Cloudflare dashboard, experienced an outage for up to 2 hours and 22 minutes on June 12, 2025.
