<br>
I won't bother arguing whether or not ICANN has the &quot;skills and<br>
experience, the resources, and the need, to deliver the [Root Zone<br>
Maintainer] function&quot; (hint: it isn't rocket science and ICANN already<br>
does). I will simply note that in many (most?) situations in which an<br>
operational infrastructure is considered important, there is a requirement<br>
for a &quot;Two Person Rule&quot; (<a href="http://en.wikipedia.org/wiki/Two-man_rule" target="_blank">http://en.wikipedia.org/wiki/Two-man_rule</a>). For<br>
example, it would be cheaper, easier, and far simpler if there was a<br>
single person in nuclear missile silos able to launch the missiles, yet<br>
there is a requirement for two people with two keys to enable launch.<br>
<br>
Further, if you have two party controls (and you assume a base level of<br>
competence), it does not matter who performs the functions as long as they<br>
are different: the two parties provide checks to minimize the risk that<br>
either party has the ability to unilaterally either accidentally or<br>
maliciously &quot;do the bad thing&quot;.<br>
<br>
It is true that it is not technically essential to have two party<br>
controls, nor is it the most efficient way of operating, however I<br>
personally believe it is appropriate in the context of the root zone.&nbsp; How<br>
that is actually implemented should be a topic for future discussion.<br>

<p class="MsoNormal">&gt;Dear Alan, Dear CWG&nbsp; colleagues:<br>
&gt;<br>
&gt;1.&nbsp; &nbsp; &nbsp;I think that it is not technically essential to have separate IANA and<br>
&gt;RZM operators. It is visually preferable and in certain limiting cases<br>
&gt;more secure, provided that an appropriately independent RZM operator can<br>
&gt;be identified.<br>
&gt;<br>
&gt;&nbsp; &nbsp; &nbsp; &nbsp;In any event, absent the NTIA contract,&nbsp; it would be entirely<br>
&gt;inappropriate for any Registry or Registrar with a corporate interest in<br>
&gt;the content of the Root Zone to become or remain RZM operator.<br>
&gt;<br>
&gt;2.&nbsp; &nbsp; &nbsp;I agree with Alan's question. I have also been perplexed as to the<br>
&gt;motives for the explicit and implicit attacks on IANA performance in the<br>
&gt;CWG. If it not evidence-based, then Why?<br>

&gt;&gt;<br>
&gt;&gt; Milton has asked (several times) WHY we want to ensure that the IANA<br>
&gt;&gt;Functions Operator and Root Zone Maintainer must be separate entities.<br>
&gt;&gt;The answers I have heard to date do not (in my mind, or presumably<br>
&gt;&gt;Milton's) really explain why the two-party solution is better. With the<br>
&gt;&gt;current architecture, most or all errors that Verisign could catch would<br>
&gt;&gt;also be catchable in a single-party implementation.<br>
&gt;&gt;<br>
&gt;&gt; Can anyone provide either a general answer or specific scenarios where<br>
&gt;&gt;the two-party solution is better.<br>
&gt;&gt;<br>
&gt;&gt;<br>
&gt;&gt; 2.<br>
&gt;&gt;<br>
&gt;&gt; 1.c.1 Says that we need to consider increasing robustness WITHIN IANA<br>
&gt;&gt;prior to the CWG proposal being submitted.<br>
&gt;&gt;<br>
&gt;&gt; 1.c.2 Says we need to consider robustness everywhere (including within<br>
&gt;&gt;IANA) post transition.<br>
&gt;&gt;<br>
&gt;&gt; I am not aware of the justification for 1.c.1 other than it was sort of<br>
&gt;&gt;implied by the transfer of tasks from DT-D. But since NTIA did not<br>
&gt;&gt;refuse authorizations and there are no known problems, it is not clear<br>
&gt;&gt;that this is an urgent matter.<br>
&gt;&gt;<br>
&gt;&gt; Moreover I find it highly unlikely that a proper job of this could be<br>
&gt;&gt;done prior to transition if it occurs in 2015 or early 2016.<br>
&gt;&gt;<br>
&gt;&gt; Do we want to keep it?<br>
