Fill out the form and submit. I get the following error after more than 30 seconds:
502 Proxy Error
The proxy server received an invalid response from an upstream server.
The proxy server could not handle the request POST /tools/feedback.
Reason: Error reading from remote server
Apache/2.2.21 (Linux/SUSE) Server at http://www.lds.org Port 80
Also your version of Apache is out of date and has known security issues. It should be patched.
