Last Modified : 10/24/2023


On March 31, 2023, at 08:00 MDT (14:00 UTC), DigiCert will assign new dedicated IP addresses to the online certificate status protocol (OCSP) for our PKI Platform 8 services.

What do I need to do?

Does your company use allowlist?

  • If not, no action is required. Your services will continue to work as they did before the addition of the new IP addresses.
  • If yes, you need to add the new IP addresses to your allowlist by March 31, 2023, to keep your PKI Platform 8 OCSP services running without interruption.
