What does DNS request timed out mean?

A few months ago slashdot had and article/link on the Juggernaut search
engine.  It's a GPLd web crawler in perl.  I visited the web page once,
about 3 weeks ago, and I liked it.  Today, when I went to download it, I
get a 

DNS request timed out.
	timeout was 2 seconds.

when I try to access their site.  The URL is:

http://www.juggernautsearch.com/cgi-jugger/juggernaut.cgi

What does this mean?  What could cause someone to lose their DNS entry
(excluding doing something stupid like not paying cough... microsoft...
cough... hotmail... cough, cough).  Could it be a local problem with CSU
DNS servers, or did I miss my chance.

I can't find anything about it on google either.  If anyone did download
this, could I get a copy?

Here's a kind of stupid question:  did you try to hit it again? I've
seen a /lot/ of times when the DNS call will timout before a reply
makes it back.  On the second call, though, the name is all cached
up, and returns pretty quickly.
Its a growing problem, if I see things right... but I don't know what
caused it.  I started having this problem about two years ago, and
recently, its been happening on my servers at work...

<shrug> The Internet is getting too crowded...

Please, give me a little more credit than that!  I guess I do ask a lot
of stupid questions on this newsgroup (once I asked what an ATM card
was...), has it earned me a reputation?  Yes, of course I've tried it
twice.  And twice again.  And again this morning.  Is there a way to set
the timeout on an nslookup (I'm setting at an NT box here, no man
pages)?  Netscape waits about 10 seconds before it gives me an error
message.  Is it trying multiple times, or does it set a longer timeout?

The good news is that whois reveals that juggernautsearch.com is
registered with Network Solutions and was last updated 23-sep-1999.  It
reveals two nameservers (ns[1|2].playmate.nu), neither of which respond
to a ping.  Okay, now something new is happening.  nslookup waits for
55.62 seconds and responds that juggernautsearch.com doesn't exist.  A
traceroute to either of the nameservers completes the 1st 14 hops
successfully, drops the middle packet on the 15th hop, and drops all
three packets for hops 16-30.  The 1st and 3rd packets on the 15th hop
completed in 30/35 ms.  The 15th hop is gige-g9-0.gsr12012.sjc.he.net 
The first two octets of it's IP match those of the nameservers.  he.net
is Hurricane Electric Internet Services and they're running apache. 
I've e-mail their tech support.  Anyone have any more ideas for me. 
I'll be dammed if I have to write my own robot.  Anyone know of another
free robot for perl or something I can run on win32?

Perhaps http://www.searchtools.com/tools/tools-perl.html will have what you're
looking for.

No, no... I was just wondering if it was possibly that problem.  I'll 
see what I can find about the DNS thing once I'm on my own servers.

If there is a way to set the nslookup timout, I'd like to know it. I
fear, however, that it wouldn't help, owing to the recursive nature
of DNS.  Your request would just timout somewhere else...

I dunno if its ported to Win32 yet (I assume it is) but the Excite engine
is avaialbe.  It doesn't show up prominently on their web page anymore,
but I can probably drop the link to you after I get to the office.

Forgive the english, typing, etc.  Windows telnet, vi, and high latency.

Okay, not this is getting scary.  I couldn't find ctoons.com this
morning.  The first nslookup gave me a Non-existant host/domain.  A 2nd
one a few minutes later gave me a no (A) record available.  A lookup for
www.ctoons.com says Non-existant host/domain.  Now, this is an address
I've visited every day for the past two years.  juggernautsearch.com
still says Non-existant host/domain, but now it returns almost
instantly.  Wait, at least it did the 1st time; now it's taking a
while.  I'm using hugo.acns, BTW.  I was using yuma yesterday.  Hey, I
just noticed a mistake in my resolv.conf (100.63 instead of 100.64).

I got a record at internic that pointed to netsol.
Netsol says that Juggernautsearch.com is listed at playmate.nu domains.
When I seach there, they don't return any names for juggernautsearch.com.
So, the problem is somewhere at playmate.nu

Hmmm... ctoons.com is registered to ctoons.com and wave-inc.com.  Neither
of these name servers respond to nslookup.  Since both of their nameservers
are down, they are pretty much kicked off the net.  Bummer.

FWIW, you can often replace the 100 with a 103 and still get to the same
computer.  The 103 subnet is a backplane between the big machines.
Another useless fact.  Woo.
