To use this hook you must use the SUNRISE file.
https://docs.wpvip.com/wordpress-on-vip/multisites/sunrise-php/
```
// located in ms-settings.php
if ( defined( 'SUNRISE' ) ) {
	include_once WP_CONTENT_DIR . '/sunrise.php';
}
```
Add define( 'SUNRISE', true ); to the wp-config.php.

Then create a file in the /wp-content/ directory called sunrise.php.

You can then access the ms_site_not_found action.
```
// inside sunrise.php
function wpdocs_ms_site_not_found( $current_site, $domain, $path ) {
	global $wpdb;

	// DO STUFF....

}
add_action( 'ms_site_not_found', 'wpdocs_ms_site_not_found', 10, 3 );
```
