I don't this it was because I clear cache, cookies, and history every time I close my browser. It's a pita, but, it is one of my few compulsions. I could also ping he site at the same time. When I checked again after I made my posts, I could no longer ping the server and got the connection timed out messages. I had checked the site many times since it went down and that was the only time out of 20-30 times I tried over te last few days.
