Domain Monitoring
Your TLS certificate can be perfect and your servers healthy — and you'll still go dark if the domain registration lapses. Domain monitoring watches the registration itself via WHOIS and warns you long before the expiry date, so a missed renewal invoice never becomes an outage (or a lost domain).
How it works
On each run the checker performs a WHOIS (and RDAP where available) lookup for your domain and records:
- Registration expiry date and days remaining.
- Registrar and domain status codes (e.g.
clientTransferProhibited,redemptionPeriod). - Nameservers currently on record.
Because registration data changes slowly, domain checks run on a daily cadence.
What triggers an alert
- Expiry warnings fire at tiered thresholds — commonly 60, 30, 14, 7, and 1 days before expiry — escalating as the date nears.
- The domain has already expired or entered a redemption / pending-delete status.
- The registrar or status codes change unexpectedly (for example, a
Holdstatus that would suspend resolution).
Renewing with your registrar clears the warnings on the next daily lookup.
Setting it up
- Add monitor and choose Domain.
- Enter the registrable domain (e.g.
example.com— not a subdomain). - Confirm the warning thresholds or adjust them to match your renewal lead time.
- Attach notifications — route these to whoever owns billing/renewals.
WHOIS coverage varies by TLD. A few registries rate-limit or redact expiry data; where the date is unavailable we surface status changes instead and note the limitation on the monitor.
