The registry’s own Updated Date
Every registry keeps a timestamp of when a domain’s record last changed. We read it on every check and tell you when it moves. Registrar changes, nameserver changes and status changes we already name individually — this catches everything else the registry recorded: a DNSSEC key swap, a contact edit, a renewal. Whoever gets into a registrar account doesn’t always start with the nameservers, and the quieter steps still leave this trace.
It costs nothing extra to watch. The value arrives in the same response as the expiry date, the registrar and the nameservers — last changed in RDAP, Updated Date in WHOIS — so there is no additional query to the registry. It’s compared against the stored value on every daily check, and on any manual re-check you run yourself. Times are shown in UTC, exactly as the registry publishes them.
What moves it
What lands in the registry record depends on the zone. For .com and .net the registry is “thin” — nameservers, statuses, registrar, dates and DNSSEC — and contact details live with the registrar, so editing them doesn’t move the date. For .org, .info and most country domains the registry is “thick” and holds the contacts too, so a contact edit does move it.
What it doesn’t tell you
- It says the record changed, not what changed. Reading the detail is a trip to your registrar account — this is the prompt to make it.
- Ordinary events move it too. A routine renewal shifts the date. That’s a fact, not an alarm.
- Not every zone publishes it. Where the registry doesn’t provide it, the field stays empty and nothing is ever raised from it — a dash in the interface says so plainly.
- The field is always shown; the alert needs monitoring on. You can read the date on any domain you’ve added, but a change only reaches you when WHOIS monitoring is switched on for that domain.
How it reaches you
There is no separate email for it, on purpose. The change joins the same WHOIS-changes notification that lists every difference found in one place — if the nameservers moved and the date shifted, that’s one message with both, not two. Old and new values are shown to the minute, and it goes to email plus whatever channels that domain’s notification group uses.
