Dropped right down listing for no reason

[jrh10]

I hope someone can help, i am web designer and have ran the site www.crb.gb.com for a client for over 5 years.

In that time the site has always been well listed in Google, searches for "custom peptides" and the company name "cambridge research

biochemicals" always brought the site up near the top of the listings.

The client has used adwords for around a year to increase coverage for specific words and recently also started using overture for other

search engines.

Over the last month however the site has dropped dramtically off google - searching for the company name or specific phrases just

don't bring up the site - in fact the only way to get the site to display is to actually search for the web address (crg.gb.com).

What could be causing this problem - when i search for site:crb.gb.com i can see google has over 50 pages from the site indexed and

all within the last two weeks.

What can be causing this problem - the site has a page rank of 5 which it has had for a long time.

Any ideas would be very much appreciated.

Thanks
Jon

The site can not be found... check your hosting uptime...

I have been running a few of my websites for quite a while and have had lots of traffic and on top of the search engines with reciprocal, reciprocal links, reciprocal links directory, links directory and many other sub directory keywords: www.newworldproducts.org .. For some darn reason google.com is being a total A#$ and therefore is destroying my page rank
