Tracking Down Traffic..?

[subtle]

Hey all, lately we have been getting real unexpected traffic to our website... Like im talking an increase of 23,000%. Analytics and our CMS platform arent providing any information about wherre this traffic is coming from. Is there a way in which I can find out exactly where this traffic is coming from?

All help is appeciated.

Do you have access to the server logs, or have any reporting tools on the web server it's self?
