Domain expiry monitors

Checks a domain’s registration expiry once a day via public registry data (RDAP), cached aggressively to respect registry rate limits.

Same 30/14/7/1-day warning schedule as SSL expiry. An unrenewed domain takes the site, email, and every service on it down at once — this is the cheapest insurance in the product.

Some country-code TLDs don’t publish RDAP data. When that’s the case, the monitor shows an “expiry unknown” badge rather than guessing.
