Will there be changes to the Zendesk admin cert notification that reflect changes to Transport Layer Security (TLS) certificate lifespans as mandated by the Certification Authority Browser Forum (CA/Browser Forum). The CA/BF has established a phased approach to shorten the maximum allowed lifespan for new certificates:

  • Until March 15, 2026, the maximum lifespan is 398 days.
  • As of March 15, 2026, the maximum lifespan is 200 days.
  • As of March 15, 2027, the maximum lifespan is 100 days.
  • As of March 15, 2029, the maximum lifespan is 47 days.

I want to make sure that anyone managing our Zendesk is appropriately notified when certs are updated and have not seen an announcement about this notification feature being updated. Is it currently a time-based trigger, or does the notification trigger based on the actual expiration of the uploaded cert?
