Welcome to the Q&A Forum

This made me say "What!" With some other words following. http://moz.com/community/q/https-sitewide-move-has-resulted-in-huge-rankings-drop Not specifically SEO, but when comments nowadays suggest link farming, also makes me go "What". What makes you say 'what', White?

If it were me I would use something like web-sniffer.net to try to simulate google bot and see what that does. I would also verify that the file is on the server by looking in the ftp for it. If it is, then I would look in the htaccess file and see if there is anything set regarding it. Someone might have it set up to only let bots view the file, which in itself is not really a bad idea.

Perfect, thank you both for your help.

Yeah, I use iframes and if I want to be sure they are NOT indexed, I Just add a "noindex" tag. You may also want to add a "nofollow" tag to avoid spiders to follow links inside the frame. Using iframes may be a good idea to reduce the number of links on a page (Bruce Clay suggestion).
