DNS troubleshooting
DNS troubleshooting for business websites and services
DNS problems can look like “propagation” when the real cause is a wrong authoritative nameserver, stale delegation, conflicting record, proxy setting, DNSSEC failure or an application pointing at the wrong endpoint.
Nameserver and delegation problems
Check whether the registrar delegation and authoritative nameservers agree and respond consistently.
A, AAAA and CNAME mistakes
Validate whether hostnames resolve to the intended target and whether conflicting records exist.
Propagation confusion
Separate real DNS cache delay from an incorrect zone, delegation or resolver-specific problem.
Production impact
Confirm whether DNS is actually the failing layer before changing records during an outage.
