Someone in India decided to get all the pictures, but not use the compressed archives. Probably just to test his/her scripting-skills. This resulted in 43194 hits from one ip-address in 6 hours. This defeats the previous webhits record by far.
Just so others can do this too, I'll try to explain all the things that I've done to run this website on a machine that is in the cupboard that also holds my fusebox.
I've aimed at minimum energy usage, but it still had to have some power. The current hardware is capable of streaming HD-movies to my mediaplayer and a pc at the same time and handling the website and mail.
