<p class="MsoNormal">I agree with Olafur. The KSK rollover should be considered an overall success. Coming from a community where there is a vocal minority that only grudgingly deployed, if there was a significant issue with the rollover we would have heard
about it. There could be improvement, but overall it was successful.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I also agree that we should start looking at post-quantum algorithms in DNSSEC. NIST has an effort underway now:<o:p></o:p></p>
<p class="MsoNormal"><a href="https://csrc.nist.gov/Topics/Security-and-Privacy/cryptography/post-quantum-cryptography">https://csrc.nist.gov/Topics/Security-and-Privacy/cryptography/post-quantum-cryptography</a> There isn’t anything available that could be
suggested, but it is an effort I intend to follow. A breakthrough in quantum computing could mean everyone needs to rapidly deploy of a new algorithm.

<p class="MsoNormal">Main lesson from this roll is it worked better than we could have expected, given this was the first time,<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">We expect that software/configuration has bugs/errors and this exposed some.<br>
There might have been some configurations that did not anticipate change in the key used ==> nothing beside rolling the KSK could have exposed that. <o:p></o:p></p>

<p class="MsoNormal">There were some outages, there may have been some sites that turned off DNSSEC<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">and we need to get some measurements of what that long term effect was i.e. did the validation get turned back on. <o:p></o:p></p>

<p class="MsoNormal">The traffic increase reported was interesting but the big picture is it was in the NOISE range, i.e. all root servers should be able to deal with such small increase. <o:p></o:p></p>
