http://vimhelp.appspot.com/vim_faq.txt.html currently shows:

"This application is temporarily over its serving quota. Please try again later."

A Google search for "vim faq" shows:

http://vimdoc.sourceforge.net/htmldoc/vimfaq.html

But it says the latest version is 6.3, which was released in 2004. I don't know whether there's a newer version of the FAQ.
