DigiCert probably should have revoked every cert they could within 24 hours. Instead they just pushed the revocation of all 80,000+ certs out to five days.
It's quite likely that many of their other clients pushed back on the 24-hour timeline (similar to what happened in their previous incident); I believe the delayed revocation issue (https://bugzilla.mozilla.org/show_bug.cgi?id=1910322 https://bugzilla.mozilla.org/show_bug.cgi?id=1910322) hints at this. The TRO gave them a convenient excuse to delay all revocations without having to explain all over again why they made exemptions for their special clients.
Heck, their status page (https://status.digicert.com/incidents/3sccz3v31lc9 https://status.digicert.com/incidents/3sccz3v31lc9) even gives instructions for how to request a delayed revocation - even though the initial incident page (https://www.digicert.com/support/certificate-revocation-incident https://www.digicert.com/support/certificate-revocation-inci...) says clearly:
"Any issue with domain validation is considered a serious issue by CABF and requires immediate action. Failure to comply can result in a distrust of the Certificate Authority. As such, we must revoke all impacted certificates within 24 hours of discovery. No extensions or delays are permitted. We apologize if this causes a business disruption to you and are standing by to assist you with validating your domain and issuing replacement certificates immediately."
