Cisco Umbrella (Formerly OpenDNS)
I just wanted to create a little post about good ol' Umbrella.
Referencing this article: https://community.cisco.com/t5/umbrella-announcements/cisco-umbrella-transitioning-from-digicert-to-identrust/ta-p/5281257
It seems our Org was transitioned ahead of time (around May 6th). All of our connectors went down. It seems umbrella was blocking "identrust.com", and as a result certificate revocation was failing causing token renewal errors. After we whitelisted this domain, all of our connecters were able to resync.
But here's the kicker (according to the article):
- Announced: April 14th 2025
- Delayed: April 29th 2025
- Delayed: May 29th 2025 (Until August 2025)
- To begin: March 16, 2026 (May 15, 2026)
- Delayed: April 22, 2026 (Until October 2, 2026)
So even though they never transitioned orgs officially, we were transitioned prior to May 15th even though it was then delayed to October 2nd. Ironically the domain "identrust.com" was still passing policy tests too.
