Welcome to WebmasterWorld Guest from 188.8.131.52
Someone on a site whose name I don't think I can mention here just reported that they can't find their site suddenly either. I wonder if they are seeing the same problem I am. Two people responded to that post though, and said it all looks ok to them. (I would respond over there, but I am out of town and can't find my password)
Maybe just people in some regions are seeing it? I'm in the US.
