Drop-ins are files designed to replace, add, or enhance specific WordPress core features.
A limited set of drop-ins are provisioned for all WordPress environments on the VIP Platform by VIP MU plugins:
db.php: Using Automattic’s HyperDB database class.
sunrise.php: Customers can modify
sunrise.phpby creating and editing a
client-sunrise.phpfile in their application’s wpcomvip GitHub repository.
No other drop-ins can be added to a WordPress site. If a drop-in is added to an application’s GitHub repository, it will be ignored by the environment.
The Automattic-authored “Maintenance Mode” plugin is the suggested alternative to the commonly used
maintenance.php drop-in. The Maintenance Mode plugin can make a site temporarily inaccessible to public traffic until site maintenance is complete. A customized page template and messaging can be served to users while the plugin is enabled.
