URGENT
DigiCert replaced multiple intermediate CA certificates (ICAs).
We replaced ICAs to:
Certificate Authorities (CAs) use intermediate CA (ICA) certificates to issue certificates such as your SSL/TLS certificates. The ICA certificate links your certificate to the trusted root certificate enabling browsers and other applications to trust it.
No action is required, unless you do any of the following:
If you do any of the above, we recommend updating your environment as soon as possible. Stop pinning and hard coding ICA certificate acceptance or make the necessary changes to ensure certificates issued from the new ICA certificates are trusted (in other words, can chain up to their ICA and trusted root certificates).
Rolling out new ICA certificates does not affect existing certificates. We don't remove an old ICA from certificate stores until all the certificates issued from it have expired. This means active certificates issued from a replaced ICA certificate continue to be trusted.
However, it does affect those certificates if you reissue them, as the reissued certificate is issued from the new ICA certificate. This means you will need to include the provided ICA certificate when you install the reissued certificate.
We recommend that you always include the provided ICA with every certificate you install. This has always been the recommended best practice to ensure ICA certificate replacements go unnoticed and to make sure certificates are trusted.
DigiCert replaced the ICAs listed below on November 2, 2020. We encourage you to update key stores, needed code, and certificate pinnings that may be in use.
To download copies of intermediate CA and root certificates, see the DigiCert Trusted Root Authority Certificates page. This is an active page that we update as roots and intermediate CA certificates become publicly available.
