Kia ora! Following the DNSSEC chain validation issue for .nz domains on 29-31 May 2023, InternetNZ has published a technical incident report. https://internetnz.nz/news-and-articles/dnssec-chain-validation-issue-techni... In the report, we identified the cause of the issue, which is a misalignment between our existing DNSSEC signing configuration policies and the resulting Delegation Signer record Time To Live from the InternetNZ Registry System zone build process. The report also considers other contributing factors and describes the scale and timing of the incident, as well as our learnings and next steps. In addition to the internal review, InternetNZ Council is also commissioning an independent review to examine the events leading up to the incident and our response, and to make recommendations to prevent similar failures in the future. We’ll inform you as soon as the completion date for this review is known, and the resulting report will be published. Please reach out to registry(a)internetnz.net.nz of you have any questions regarding the technical incident report.
