Domain expiration checks

Create a Domain check with a bare domain name, such as example.com. Do not include https://, a path or a port. Enter positive warning and critical day thresholds; critical must be less than warning.

Setting	Behavior
Name	Required
Domain	Required bare domain
Warning days	Remaining days at or below this value make the check degraded
Critical days	Remaining days at or below this value make the check down
Schedule	Fixed hourly lookup; not configurable
Notification groups	Assigned groups receive incident/recovery alerts

For example, warning 30 and critical 7 produce degraded health at 30 days remaining and down health at seven days remaining. An expired domain is down. The thresholds are inclusive even if a form label says “fewer than.”

Inspect the recorded expiration date after the first lookup. An unavailable, rate-limited or unparseable lookup is not treated as proof of expiration. If no new date is available, the lookup does not independently change health; check how recent the last valid date is.

Pingstack monitors registration expiration; it does not renew domains, change registrar settings or verify that auto-renewal will succeed. Keep registrar notifications and payment details current as an independent safeguard.
