weird world 156 error

[sik of it]

Hey when i tried the url:

http://world156.runescape.com/

i got the generic IE6 "page cannot be found" error page... weird thing is I'm using firefox 3??? Any ideas why this would be... do you get this too?

EDIT: Even talks about changing IE's settings to fix this problem so definately not generated by firefox!

Wasn't it a hidden world? Cause jagex shut those down or something.
