The previous profile expires today, January 20th.
The new .mobileconfig files now support MacOS >=26.1, which did not work with the previous (2025 -> 2026) files due to a breaking change introduced in MacOS 26.1.

2/2-The outage duration varied, but some sites were sporadically or entirely unavailable during between 12:50-13:45 UTC. Most Quad9 locations were not in the set, but notable cities that were in the change group: Bogota, Frankfurt, Turin, Miami, Athens. This issue created delays or missed query responses for ~ 12% of our user community. We apologize for the outage to those users who saw problems, and we have identified and resolved the root issue so this is not a repeated failure condition.

2025-01-30 15:40:11 UTC

1/2 - Quad9 experienced a significant outage in some points of presence today while replacing/updating core software components in our resolver stack. We repeatedly performed this update on smaller portions of our network without experiencing any problems, as part of a normal incrementing change cycle. However, when we moved to this larger group of systems there were issues with automatic health checks which caused withdrawals of service in some locations.
