I never noticed that my index.php when browsing to the domain-root (so www.switchbl8.nl) did not work and gave an error 403.
It took some puzzling and because all other stuff worked I knew it must have been since the transition to fcgid (instead of mod_php). I recalled blogging about it, checked my configs for errors, and found one (no plus signs in the options section).
Now it works. It’s not a special page, but it annoyed me that it didn’t work.
Next puzzle.
