Some problems are real but not urgent. They produce a warning and the monitor stays up:
- A certificate expiring within your warning window (default 14 days).
- A domain registration expiring within the window (default 30 days), or carrying a status such as pending delete.
- DNS records that differ from the last set we saw. After the warning the new set becomes the baseline, so you are told once per change.
- Slow responses.
Warnings go to your step-1 channels at most once per day per issue. Expired certificates, expired domains and missing expected DNS values are different: they go through the normal confirmation and open incidents.
