Calendar subscription with expiry dates
Under Settings → Organization → "Calendar subscription" you generate an ICS address (owners and admins). It contains, per domain with a known expiry date, an all-day event "Domain expires" and per certificate an event "Certificate expires", each with client, registrar or issuer and a link to the dashboard, with reminders 14 and 3 days ahead, in the time zone and language of the organization. Calendar apps refetch the file every 12 hours.
- Add it in Outlook, Google Calendar or Apple Calendar as a subscription by URL, do not import it, otherwise the calendar goes stale.
- The address contains a token: "New address" invalidates the old one, "End subscription" switches the calendar off. Anyone who knows the address sees the expiry dates.
- One calendar per organization; incidents and maintenance windows are not included.
