<div dir="ltr">
<div>Until a few hours ago, I had several domains and 3 nameservers for them:</div>
<div><br>
</div>
<div><a href="http://ns1.virtualbit.it" id="LPlnk59927" class="OWAAutoLink" previewremoved="true">ns1.virtualbit.it</a> (master, 136.243.232.142)</div>
<div><a href="http://ns11.virtualbit.it" id="LPlnk431808" class="OWAAutoLink" previewremoved="true">ns11.virtualbit.it</a> (slave, 158.69.210.19)</div>
<div><a href="http://ns2.virtualbit.it" id="LPlnk44025" class="OWAAutoLink" previewremoved="true">ns2.virtualbit.it</a> (slave, 136.243.232.143)</div>
<div><br>
</div>
<div>Then I tried to migrate to a new master, <a href="http://names.virtualbit.it" id="LPlnk229270" class="OWAAutoLink" previewremoved="true">
names.virtualbit.it</a> (46.4.38.130). Here is the migration steps I followed:</div>
<div><br>
</div>
<div>1) I configured Bind on the new server as master for all domains</div>
<div>2) I added the master IP address to the two slaves with:</div>
<div><br>
</div>
<div>masters vbitdnsmasters { 136.243.232.142; 46.4.38.130; };</div>
<div><br>
</div>
<div>zone "<a href="http://acquaritalia.it" id="LPlnk922358" class="OWAAutoLink" previewremoved="true">acquaritalia.it</a>" {</div>
<div> type slave;</div>
<div> masters { vbitdnsmasters; };</div>
<div> file "/var/lib/bind/acquaritalia.it.db";</div>
<div>};</div>
<div><br>
</div>
<div>and so on for all other zones.</div>
<div><br>
</div>
<div>3) I updated the NS records in the zone files, and in the control panel of the domain registrar</div>
<div><br>
</div>
<div>Now all the domains have problems. IntoDNS reports:</div>
<div><br>
</div>
<div>"</div>
<div>Nameservers A records ERROR: Some of your DNS servers do not have A records at all. I could not find any A records for the following DNS servers:</div>
<div><a href="http://ns2.virtualbit.it" id="LPlnk38922" class="OWAAutoLink" previewremoved="true">ns2.virtualbit.it</a></div>
<div><br>
</div>
<div>You must have A records for all of your nameservers.</div>

<div><br>
</div>
<div>However:</div>

</div>
<div>all work as expected. Meanwhile, the same queries against 8.8.8.8 sometime work, sometime reply SERVFAIL.</div>
<div><br>
</div>
<div>I don't know what I did wrong. Please help.</div>
