In case anyone is using certificates from DigiCert they are revoking 14
intermediate CA's after an audit of DigitCert's intermediate CAs for
extended validation certificates (EV) has revealed an inconsistency.
This revocation is going to happen by Saturday July 11, 2020 at 18:00 UTC.
See
https://knowledge.digicert.com/alerts/DigiCert-ICA-Replacement for
details.
