That web site "http://www.whatsmydns.net/", 
seems to be pretty handy. 

My results (a picture) have been placed here: 
http://www.facebook.com/photo.php?pid=4086870&id=664267723
... OR (if you do not have a facebook account [password] ), then you might need to use this "free for all" URL: 
http://www.facebook.com/photo.php?pid=4086870&l=59c7504c82&id=664267723 
(they call it a "public link".)

Does this tell us anything? 
It seems suspicious to me.

That could turn out to be a key item of info... 

Btw, "Craig White" <craigwhite@azapple.com>'s answers differed from mine.  (Maybe a "DNS" issue!)  His middle result was "#fails" (which I also got), but as for his 1st and 3rd, his results were "backwards" from what I have been seeing -- in regard to that #works / #fails metric units. 
(unless he had some typo?  naah... :-) 

Also, things seemed to work fine for Dazed_75 <lthielster@gmail.com> and "Stephen" <cryptworks@gmail.com>.  So there seem to be a bunch of things that "could" have gone wrong, that did not... 

and I am still observing some "#fails" 
(at least with a Chrome browser; -- but I am starting to suspect that this is "NOT" a "browser"-related issue)

FWIW, I am using Qwest DSL. I am not sure how to determine what my DNS server is... Hmmm...  

Well, I did a search, and just as I was going to "http://www.whatsmydns.net/", all of a sudden, my (DNS?) problems toggled, and now my results match Craig White's results! 

Is that a bit suspicious?  Or maybe just a coincidence?  Hmmm...  
Maybe it could "tell" us something...

PS:  
Is http://www.plug.phoenix.az.us/ maybe a bogus domain name? 
(Did Craig White just [erroneously] "make up" that domain name?)
