As RSSAC-002<br /> itself also explains, the goal of providing this metric was "to detect<br /> any trends in the growth of the zone". Of course serious issues like<br /> truncated zone files are a different thing altogether, but size<br /> differences related to compression differences could occur.<br /></blockquote><br />In between the text Duane quoted, and what you've quoted above, RSSAC002<br />says:<br /><br />"The size of the compiled root zone is not expected to change from<br />operator to operator; but in an effort to ensure consistency in the root<br />system all operators should report the size of the root zone so if there<br />are any differe!
