Please report this in this topic. Also, in your reply to that topic be sure to mention that this is being experienced through the Web Filter, not through the DNS. I will therefore move this post to Resolved, as this is best handled through that topic.
However, if you find that this is not fixed within 4 days please be sure to send me a PM letting me know. I will then look into this matter and see if there is another way I can report this. However, as far as I know this should be the fastest way to correct this issue.
