I get this same thing. At times I can't view my site for whatever reason but everyone else can. It does not make a lot of sense. I figured it had something to do with my IP Address. But it seems as it is an entirely different issue. Now, I am also hosted with Citrex, so the problem may be on their end. However, I am on a dedicated server so i have no idea.

Anyone else experience this issue? I will say when this does happen if I refresh the page really fast the site catches and shows.
