Your first shortened TLS certificates expire in September

Public TLS validity dropped from 398 days to 200 days on March 15, 2026, the first of three cuts on the way to 47 days in March 2029. Most CAs moved early, so certificates issued from late February onward begin expiring in September and through October. By 2029 that works out to roughly eight renewals per certificate per year.
