Google 404 Error page – title error ?

Recently I was trying to connect to Google Plus using invite. it always gave me 404 ( Page not found error ).

While sadly looking at this page, I have noticed something different in the title bar of this page. It says

Error 404 (Not Found)!!1

instead of ( I guess )

Error 404 (Not Found)!!!

 

Also I think that the previous Google 404 error page was much more detailed then this one. This one looks good in terms of design, but just saying 404 that’s an error, and That’s all we know does not much help the user.
