My God.  THis is so wasteful of everyones time and effort.

Here is a (l)user who is inside a network environment claiming that 
something is happening in the outside environment but providing nothing for 
anyone with any technical expertise on an external network to verify any of 
the claims.

This is PURE defamation and total arrogance.

Craig stop wasting peoples times with hypothetical "my network is broken" 
threads and replies unless you are prepared to publish the domain name that 
is apparently broken, the IP addresses of your name servers, the ip 
addresses of the alleged intercepting name servers and any other details 
that us Linkers with more knowledge and experience than you can actually do 
some tests OUTSIDE your toy network with so much interception and filter 
crap on it I'm not surprised you can't connect to the rest of the world.

Craig, Put up or SHUT THE * UP.

I'm not even going to comment on "I've been a Sys Admin in the ISP industry 
since the 1990's" my god, the number of ISP admins that are unemployed or 
out of business from that era is no surprise.
