My top two would be that either 8.8.8.8 is down (hee, hee ;-) or that your Internet connection is down. I'd guess number two is the case. So I'd guess that it's not only your DNS resolution failing. Whenever your DNS fails try a "traceroute 8.8.8.8". Compare its results to what you get when you do it at times where your DNS works. Perhaps this sheds some light on it. Cheers -- tomás
