We were a young startup we went to a conference... when the site went down and we found someone DoSing us. But... there was little network traffic however the database was loaded beyond any reason. Turns out, the image importer from mail had a bug in error handling and a broken email came in so it just kept retrying creating an image entity in the database. Ten thousand broken images before we stopped the party, in 2005, that was enough to crash our little server. We DoS'd ourselves.
