Just here or everywhere? I haven't seen that anywhere. Could be your DNS temporarily acting stupid.

I have one from the public DNS Level 3 (4.2.2.1 to 4.2.2.6) and one from Google (8.8.8.8 or 8.8.4.4) in my Network prefs, in case one of the services is down it will go to the next, and because they are better than my ISP. I get that stupid advertising crap sometimes with my ISP as primary and they are slower. I do let the router grab the ISP just in case the other two aren't working, Anal DNS'ing. grin
