Just guessing, but I suspect that if you look in your referrer logs,  
you'll find that a search engine was indexing your site at the time.   
If so, you'll need to adjust your robots.txt file.  Note that once  
the spidering starts, some or all of these don't recheck the robots  
file for changes.  I was sufficiently annoyed at the rate MSN was  
indexing my sites so that I just added a code snippet that caused my  
wiki to crash if MSN tries to index it.
