this is the first time the cache has done a query for this domain, then the query will go to nscp1/2.intertech-pal.com. However if it has previously done a query, it will have cached the NS record from within the zone. Depending on the software they're running,
some caches will *merge* the NS records from the delegation and within the zone; other caches will *replace* the NS records with those within the zone, and only send queries to ns2.cmeac.net from then onwards (until the NS records expire). And of course,
with only one nameserver within the zone, there is no resilience (see RFC 2182); if that nameserver is down, clients will get only SERVFAIL.</span></span></span></span></span></p>

<p>So that's your problem: the problem is in how the zone itself is set up, not the recursor, which is behaving correctly. Once a cache has learned that ns2.cmeac.net is the sole nameserver for the zone (learned from the authoritative information within the
zone), it may only send queries to this bad nameserver.<br>

If you only want two nameservers nscp1/2, which are working and which the domain is already delegated to, then the fix is simple. Inside the zone file, remove the NS record pointing to ns2.cmeac.net and add two NS records pointing to nscp1.intertech-pal.com
and nscp2.intertech-pal.com. Job done.</span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></p>

configure all the nameservers so they have identical zone contents. Normally this is done by configuring replication. You can use DNS zone transfers, so one nameserver is master and the others slave from it; or perhaps you build all the nameservers with a

for example, suppose you want nscp1/2 *and* ns2.cmeac.net to be authoritative nameservers for this domain. You need to configure replication so that ns2.cmeac.net is authoritative for the domain *and* has identical zone contents to the other two nameservers.
Then you have to create three NS records inside the zone. Then you have to change the delegation in your registrar to point to these three nameservers.</span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></p>

that if you do want to use ns2.cmeac.net as a nameserver then you need at least one other nameserver as well; and it needs to be on a different network backbone (again, details in RFC 2182). Otherwise you can certainly expect random failures to occur intermittently.<br>
