The ageing hardware of my trusty FreeBSD server might collapse any day now. So after some market research I found a shared hosting service to run koorneef.net on. Site5 is situated in the USA, but still is quite responsive in Europe. Site5 uses Linux together with Apache, Mysql and PHP. Not too many changes needed for the switch.
I upgraded Drupal to 4.7.2 (latest release). It went pretty smooth ! I haven't installed all the modules of the previous install yet. The captcha module made it possible to switch on anonymous comment posting and the contact forms again. Visitors will have to type in a few letters from an image to post their comment.
