DNS issues

DNS troubleshooting ​

DNS issues stop your site dead. With an uptime problem the server is at fault. With a DNS failure, visitors can't find your site in the first place: the browser never makes a connection and returns "This site can't be reached." DomainDash picks these problems up at its next DNS check.

DomainDash runs DNS checks on every plan. How often they run and how long DomainDash keeps the history depend on your plan. See the plan comparison. You'll find the results on the site's Domain routing card.

Not sure which DNS issue you have? The domain not resolving page takes you from the symptom you're seeing to the right fix.

Resolution failures ​

Problems where your domain can't be translated into an IP address.

  • No A or AAAA records — the domain has no records pointing it to a server. Browsers show DNS_PROBE_FINISHED_NXDOMAIN or ERR_NAME_NOT_RESOLVED. Usually a deleted or missing record in your DNS provider's dashboard.
  • Nameservers unreachable — the servers responsible for your domain's DNS aren't responding. Could be a DNS provider outage or misconfigured NS records at your registrar.

Propagation and changes ​

Problems that appear after you've made a DNS change.

  • DNS changes not propagating — you've updated DNS but the new records aren't showing everywhere yet. Explains how TTLs and resolver caching affect propagation, and what you can (and can't) do to speed it up.

Not sure where to start? ​

  • Domain not resolving — a routing page from the user-facing symptom ("my domain doesn't work") to the specific DNS issue and how to fix it.
