Let that be a lesson to me!
Wow, my personal web site has 1500 hits already. I migrated the site to the linode on 16th May and for that half of the month there was 800 hits total.
More research… Ah hah… 3 or 4 search engines decided to reindex my site at the beginning of the month, and I have 3 cgi scripts that generate 2300 links to data views…
I think I need a robots.txt file to prevent those cgi's from being indexed!
