Jah? I never tried that one. Ragtime seems the most reliable in my experience.
The thing to do is keep all of them available, either on a home page or in favourites (or whatever you call it on your browser), and try the others. And the help one as well - that often works even when the others don't (though of course it doesn't get you to the forum, just to the help forum where you can lament that you can't get through to the normal one.)
"Wait pipes", "stack pages" - what strange jargon they have come up with, the magicians who set this whole world up.
