Matt, what happens you get on a subnet that can access the webservers directly and bypass the load balancer. Try curl then and see if its something w/ the webserver or load balancer.****

Thanks again to everyone who helped. I didn't know what to enter with curl, because Outlook clobbered the line breaks in Jeremy's original message.
Also, curl failed on our primary webserver because of firewall and load balancer magic settings. The Telnet method worked better!
Our team is now scouring for that hidden redirect to couchtarts.****

There is definitely a 301 redirect.

Running Apache on three Solaris webservers behind a load balancer. No MS Windows!
Not sure how malicious software could get between our load balancer and Unix servers. Thanks for the tip!

Is it possible that some malicious software is listening and injecting a redirect on the wire? We've seen this before with a Windows machine being infected.****

We have thoroughly examined our root .htaccess and httpd.conf files and
are not redirecting to the problem target site. No recent changes either.
We ran some NSLOOKUPs against various public DNS servers and
intermittently get results that are NOT our servers.
We believe the DNS servers used by Google's crawler have been poisoned.
Can anyone shed some light on this?
