The finding is interesting that four approaches successfully for BIND (9.11.5-P1) and UNBOUND(1.8.3) resolver. Note that there is an accidental mistake in configuring the ZSK's inactive time which results no active signing key in the middle of the rollover and causes validation failure(we recovered it with a new ZSK but it still had impact on resolver). As a response to this failure, it is observed BIND restarts the Add Hold-Down Time of new key/algorithm for another 30 days when new valid signing key is available but Unbound continue the timer and trusted the KSK/Algorithm after the rfc5011-timer expired. It is planned that more lab test for rollover should be done before roll the algorithm of Yeti. We will call for more resolvers to join this test.”</span></p><p class="MsoNormal"><span lang="EN-US"> </span></p><p class="MsoNormal"><span lang="EN-US">Best regards,</span></p><p class="MsoNormal"><span lang="EN-US">Davey</span></p><p class="MsoNormal"><span lang="EN-US"> </span></p></div></div></blockquote><blockquote type="cite"><div><span>_______________________________________________</span><br><span>ksk-rollover mailing list</span><br><span><a href="mailto:ksk-rollover@icann.org">ksk-rollover@icann.org</a></span><br><span><a href="https://mm.icann.org/mailman/listinfo/ksk-rollover">https://mm.icann.org/mailman/listinfo/ksk-rollover</a></span><br></div></blockquote></div></body></html>
