Yes. You garnered the evening's "dry humour" award.
In case people missed one particular fine point of my "dig" test:
$ dig connected.sonymusic.com @ns1.linuxmafia.com +norecurse
^^^^^^^^^^
I set the "norecurse" flag on my query specifically so that queried
nameserver ns1.linuxmafia.com would _not_ forward the request to
other nameservers, if it lacks that information.
And, Daniel, your wget fetch from linuxmafia.com's shell prompt actually
did _not_ put "connected.sonymusic.com" into ns1.linuxmafia.com's cache,
because apparently your request got routed to one of Raw Bandwidth's
nameservers, instead of to mine:
:r /etc/resolv.conf
search linuxmafia.com deirdre.org
nameserver 198.144.192.2
nameserver 198.144.192.4
nameserver 198.144.195.186
(The last of the three IPs is ns1.linuxmafia.com. Your request went to
one of the other two.)
One easy way to _actually_ load my nameserver's cache is, well, with "dig":
$ dig connected.sonymusic.com @ns1.linuxmafia.com +short
64.14.39.158
_Now_, it's in cache. ;->
$ dig connected.sonymusic.com @ns1.linuxmafia.com +norecurse
; <<>> DiG 9.3.1 <<>> connected.sonymusic.com @ns1.linuxmafia.com +norecurse
