## Timeline of updates

- **identified** 2025-06-09 13:33 UTC: We are currently investigating an issue while certain DNSSEC-enabled zones are sporadically returning SERVFAIL. Zones without DNSSEC are not affected.
- **identified** 2025-06-09 13:35 UTC: We are continuing to work on a fix for this issue.
- **identified** 2025-06-09 13:38 UTC: We are rolling back a recent deployment to a stable version of our nameservers
- **monitoring** 2025-06-09 13:59 UTC: The rollback has completed.  The nameservers that were previously returning invalid data are serving now correct responses. It might take up to the TTL value of the corresponding records to clear out cached responses.
