The Domain availability checker watches a domain name you do not own and notifies you the moment it becomes available for registration. It is the counterpart of {{< relref "/reference/checkers/domain-expiry" >}}: instead of protecting a domain you hold, it lets you grab one as soon as it lapses.
This is a domain-level checker: registration status is determined from the registry through a WHOIS/RDAP lookup. A domain is considered available when the registry reports that it does not exist.
What it checks
A single rule, domain_availability_check, reports whether the watched domain is still registered or has become free.
| Status | Condition |
|---|---|
| Critical | The domain is now available for registration |
| OK | The domain is still registered (the registrar and expiry date are reported when known) |
| Error | The availability lookup failed |
{{% notice style="info" title="Why available is reported as Critical" %}} The status is intentionally inverted compared with the usual convention. Reporting Critical when the domain becomes available makes the registered → available transition cross the notification threshold, so you are alerted exactly once when the domain frees up. {{% /notice %}}
Options
This checker has no user-tunable options. The watched domain name is supplied automatically.
In happyDomain
Unlike the other domain-level checkers, Domain availability is not scheduled on the domains you manage. It is driven by the dedicated availability-watch list. See {{< relref "/pages/domain-availability" >}} for how to add a domain to watch, and {{< relref "/pages/checks" >}} for the general checks workflow.
