Continuity steps for Entrust Limited customers
- Automate renewal with ACME. Public TLS certificates are limited to 200 days from 15 March 2026, 100 days from 15 March 2027 and 47 days from 15 March 2029.
- If you publish CAA records, include a second certificate authority you could switch to, so one issuer's problem cannot block renewal.
- Keep a list of where each certificate is installed (CDN, load balancer, origin) and how each one renews.
