The requested URL could not be retrieved

While trying to retrieve the URL: http://www.goodreads.com/

The following error was encountered:

Could not resolve Hostname "www.goodreads.com"
Some aspect of the requested URL is incorrect. Possible problems:

Hostname does not exist (or has expired)
Typo/syntax error in the URL
DNS Server problem (in which case you should try again later)

This has been happening since I installed BFilter. It only happens with some websites. And it happens even when I bypass the filter..?
It happens with big websites that shouldn't be down like facebook and goodreads etc.
Any Ideas?!
