This bug added a new OneCRL block entry for the Information Security Certification Authority, with the stated reason “Kazakhstan MITM (#8).” Kathleen Wilson opened the bug and requested that the new certificate be added after the ISCA CA PEM changed again. The OneCRL entry was created by d**********r@mozilla.com on 2021-07-08T19:58:35Z and later approved for production the same day. The thread explicitly says the key was changing each time, so blocking by public key hash would not work. The entry was verified in Firefox Nightly and Release on 2021-07-09. The thread does not state a CCADB revocation field or candidate-report state as the trigger, and it does not identify a separate CA closure; the only explicit external cause is the Kazakhstan MITM incident.
