The Let’s Encrypt team is excited to announce that ACME Renewal Information (ARI) is live in production! ARI makes it possible for our subscribers to handle certificate revocation and renewal as easily and automatically as the process of getting a certificate in the first place. With ARI, Let’s Encrypt can signal to ACME clients when they should renew certificates. In the normal case of a certificate with a 90 day lifetime, ARI might signal for renewal at 60 days.
