Will your certificate renewals survive 64-day certificates?
Let's Encrypt issues 64-day certificates from 10 Feb 2027, and every public CA stops at 100 days from 15 Mar 2027. Type a domain: we read its public certificate history and the certificates its servers send now, and tell you per hostname whether the renewals keep up.
What the check tells you
-
Per hostname
The certificate served now, how its renewals have been running, what that means on each coming date, and anything wrong today: a renewal that is overdue, a new certificate that was never deployed, a CAA record that blocks your CA, a broken chain.

The live part takes about 20 seconds. The history follows when the public Certificate Transparency search has time for it; the page shows your place in line.

Honest about guesses
A renewal rhythm read from public logs is an inference. We say "looks like", show the dates it rests on, and say "can't tell" when the history is too short.
