That implies that the zone is not stable, and we dislike non-stable zones (tends to cause excessive traffic back on our nameservers). In an idealised world, we'd generate a caution back to the requestor, and keep trying the nominated nameservers for the nominated domain until we're happy, or an arbitary timeout (a day?) is exceeded. > Speaking of the SE TLD, we always reject updates where we find any > difference in SOA serial, SOA mail address, NS records or A records > corresponding to necessary glue records between any of the nameservers. We error out on SOA serial mismatch, and simply warn on any other SOA mismatch (mail address, timeout values etc) due to some oddities in the perl DNS module. -- Bruce Campbell <bruce.campbell@apnic.net> +61-7-3367-0490 Systems Administrator APNIC
