Dear community,

We would like to inform you of an update to the publication schedule of the .CH and .LI TLD zone data.

To support faster recovery from technical misconfigurations (e.g., DNSSEC key rollovers or nameserver changes), the zone publication frequency has been increased as follows:

Previous: Once per hour, at the full hour (:00)

New: Every 30 minutes, at :00 and :30

This change has been rolled out today and is now in effect.

In addition, dynamic delegation TTL adjustments have been in place since 18 November 2025 to further improve recovery times. When delegation information (NS or DS records) is created or updated - including new registrations and delegation changes - the delegation TTL is temporarily reduced from the default of 1 hour to 15 minutes for a period of 12 hours. This enables corrected delegation configurations to propagate more quickly.

If you have any questions, feel free to reach out.

Kind regards, Daniel
