Puzzling drop to no-show in Google

[Pacific]

This site was doing well in Google until about a month ago when it disappeared. It has hundreds of pages, and is still listed well with Yahoo and MSN. Adwords were used at one time.

The site's layout is simple; the site is spiderable in that there is lots of text and few photos. PageRank shows 0 on my computer.

Question is, what the hell happened? One idea is that someone else on the same server has done a big NO-NO with Google and the server has been banned. But other than that, my head is getting all marked up from scratching...

Many thanks for your suggestions.

The site is banned in Google. There are a few reasons as why this can happen.

If you don't suspect any bad SEO techniques on the site (such as hidden text, extra "doorway" pages, etc.) then it could be that there are other domains pointing to the same content--or that the domain expired, was eventually renewed, and the content replaced.

I checked the archive.org site and it appears to have gone down around October 2004. Was that the case?

Thanks for that, bhartzer, I never thought to look in archives.org.
As far as I know, and can snoop about, there are no 'duplicate' sites of information (I grabbed some phrases on the home page, and did a search in quotes on Google for that - nothing. Well, not quite nothing. Some of the text was repeated but only in small amounts in the descriptions of links to the site.).

There are a TON of links to this site - over 400 in MSN and Google.

I guess writing to Google with hat in hand would be the next step...

It sure is banned, but I am totally stumped - I can see no reason anywhere.

This is a new tool I haven't heard of. I went to the archive.org site but wasn't sure how to look at "down time" on websites. Could you point me in the right direction?

Thanks!
