panel-generated configuration

A file on disk that ISPConfig writes out of its own database: the Nginx vhost under /etc/nginx/sites-available/, the zone in /etc/bind/pri.example.com, the system account, the backup job. Editing one by hand works. nginx -t passes, the site serves, nothing warns you. Then someone ticks a checkbox in the panel, its server daemon regenerates the file within the minute, and your location block is gone. The outage lands weeks after the edit, with no visible cause and nobody who remembers touching anything. What the panel manages, it manages alone: customisation goes through the fields provided for it — Sites → Options tab → nginx Directives — which the panel folds back in at every regeneration. dbispconfig is the source of truth; the file is only its output.
