NORTON DNS blocking a legitimate site while safeweb say it it SAFE!

Hello, I have an issue with a legitimate site that started to be blocked by Norton DNS a couple weeks ago.

 

the site is www.rds.ca is safe base on safeweb http://safeweb.norton.com/report/show?url=rds.ca&product=ask.com&action=info&source=&version=

 

And when I click the detail report of Norton DNS It gave me the result of an other sites than the one I am trying to reach

 

http://safeweb.norton.com/report/show?url=rds.cache.peer1.net

 

Could this be somekind of bug ?  I doubt there is malware present on the web site as safeweb would not rate it SAFE!
