I am going to 'assume' that you also did a dig query against the
other three google.com servers and they all answered
satisfactorily. But if you did not, you need to query ns3 &
ns4, you already got good answer from ns1 and ns2<br>
<br>
try:<br>
<br>
dig @127.0.0.1 fpdns.googlecode.com<br>
<br>
What program is running on 127.0.0.1 udp port 53?<br>

<div>From that machine, do a <br>
<br>
dig +trace fpdns.googlecode.com <br>
<br>
and analyze those results.<br>
<br>
Then try <br>
<br>
dig @ns1.google.com fpdns.googlecode.com <br>
<br>
And repeat for the other authoritive name servers
for that zone.<br>
<br>
And realize that the 'issue' might be transitive, in
other words here one minute, gone the next and that
server cached an answer when the problem was
present.<br>
<br>
I can think of several things outside your control
or your network that can cause this issue. Route to
one of Google's name servers down. Your Internet
connection was full and that traffic was dropped or
delayed enough to time out the query.<br>

Start with searching in logs of the
