Sep 1, 2026 — CPS: Adaptive Backoff support for Managed DV Validation Polling

Starting September 1, 2026, Akamai’s Certificate Provisioning System (CPS) prioritizes managed DV validation polling toward the certificates that are closest to completing.

After this change, new and recently requested certificates keep their fast cadence, and requests with the Let’s Encrypt domain validation pending for a significant period of time will be checked less often progressively over time.

For more information on this development, see the Community note on enabling Adaptive Backoff for domain validation polling.
