Users get redirected to a local warning page that does not have a pass-thru option. The redirects auto-expire after a week. Of course, people who use other DNS services than ours are unaffected.

Right now we are blocking IPs for those sites in our firewall, but this is not a great solution for us as we don’t want to load up our firewall with these types of rules, and the majority of these sites use dynamic IPs, so it’s a temporary fix at best. I wanted to see if anyone had come up with a solution for this dilemma that doesn’t involve dropping six figures on an application firewall. Thanks, -C.
