Some of you may have noticed it, but most probably have not:
the old DrupalCon sites that are still running Drupal are not accessible at the moment, they are locked by a htaccess script.
This is an unfortunate development, but in the end I didn't have any choice but to do this.
The reason for this is quite simple: the sites are unmaintained. With the associated DrupalCon, the various webteams dispersed and software updates weren't done anymore.
