whois, dig and google can't find anything on dnsreportback.com.  Are they 
possibly refering to dnsreport.com?  
http://www.dnsreport.com/tools/dnsreport.ch?domain=ccsi.com shows a few 
issues with the DNS for ccsi.com.

A dope slap is a sharp percussive blow to the back of the offender's head. 
 In this case it is intended to get their attention to fix their DNS 
entries.
 
They guys over at NPR's Car Talk (http://cartalk.com ) used to have a 
great page on the Dope Slap, including sending a virutal dope slap to 
someone that needed one.  Last time I looked, it was gone though.
