Issues with 1.1.1.1 public resolver in Canada

Started

Timeline

  1. Identified

    We have reached out to the network where we see an active hijack of 1.1.1.0/24. 1.0.0.1 and public resolver IPv6 prefixes are fully operational and reachable at this time.

  2. Investigating

    Cloudflare is aware of, and investigating, an issue which potentially impacts multiple users in Canada that use 1.1.1.1 public resolver. Further detail will be provided as more information becomes available.
