Cloudflare is investigating an issue affecting Cloudflare Gateway DNS-over-TLS (DoT) connections over IPv4. Affected customers may experience connection timeouts and failed DNS resolution. This issue is limited to DoT over IPv4. DoT over IPv6, DNS-over-HTTPS (DoH), and standard DNS over UDP/TCP are not affected. We are working to identify the cause and restore connectivity. Further updates will be provided as more information becomes available.
