all of the cases if I check the lookup with Google Public DNS

141.98.9.58 does not exist - so, a lame server resolving is

forwarders are responding with domain not found and BIND is trying
a last ditch effort of querying the roots after getting that

<p>Hi Ted.</p>
<p>Your theory sounds entirely plausible. Are you aware of the
"forward" option
(<a class="moz-txt-link-freetext" href="https://bind9.readthedocs.io/en/latest/reference.html#namedconf-statement-forward">https://bind9.readthedocs.io/en/latest/reference.html#namedconf-statement-forward</a>)?:</p>
<blockquote>
<p><strong>Grammar: </strong><code
class="docutils literal notranslate"><span class="pre">forward</span>
<span class="pre">(</span> <span class="pre">first</span> <span
class="pre">|</span> <span class="pre">only</span> <span
class="pre">);</span></code></p>
<p><strong>Blocks: </strong>options, template, view, zone
(forward, primary, secondary, static-stub, stub)</p>
<p><strong>Tags: </strong>query</p>
<p>Allows or disallows fallback to recursion if forwarding has
failed; it is always used in conjunction with the <a
class="reference internal"
href="https://bind9.readthedocs.io/en/latest/reference.html#namedconf-statement-forwarders"
title="namedconf-statement-forwarders"><code
class="xref any namedconf namedconf-ref docutils literal notranslate"><span
class="pre">forwarders</span></code></a> statement.</p>
<p>This option is only meaningful if the <a
class="reference internal"
href="https://bind9.readthedocs.io/en/latest/reference.html#namedconf-statement-forwarders"
title="namedconf-statement-forwarders"><code
class="xref any namedconf namedconf-ref docutils literal notranslate"><span
class="pre">forwarders</span></code></a> list is not
empty. A
value of <code class="docutils literal notranslate"><span
class="pre">first</span></code> is the default and causes
the server to query the
forwarders first; if that does not answer the question, the
server then looks for the answer itself. If <code
class="docutils literal notranslate"><span class="pre">only</span></code>
is
specified, the server only queries the forwarders.</p>
</blockquote>
<p>i.e. If you wanted to stop BIND from making the 'last ditch
effort', you could try setting the forward option to "only".</p>
