Maybe it's just you or something about your connection? I get that screen sometimes, but it's never a major issue and I normaly just have to wait a bit or refresh my internet connection.
Do you share your wifi with many (MANY) people? Or have some filter of some kind that could be messing with it? Perhaps you're doing it all wrong? Or, it could be the site but I doubt that.
A few people won't do what I was thinking. I was thinking MANY MANY people, to the point where wifi is seriously bad for all of them. I had this problem last year in Costa Rica, in a I think it was an apartment building.
Maybe not? That's not nearly enough to cause wifi issues.
This is a "feature" not an "error".
