While most updates of IXP Manager are quick, some may be more involved with schema updates or complicated migration steps. In these cases it's useful and advisable to put IXP Manager in maintenance mode.
Maintenance mode is now handled by Laravel's built in tool for this. You can review their own documentation for this which us copied here.
When your application is in maintenance mode, a custom view will be displayed for all requests into your application. This makes it easy to "disable" your application while it is updating or when you are performing maintenance. A maintenance mode check is included in the default middleware stack for your application. If the application is in maintenance mode, a
MaintenanceModeException will be thrown with a status code of 503.
To enable maintenance mode, simply execute the down Artisan command:
php artisan down
You may also provide message and retry options to the down command. The message value may be used to display or log a custom message, while the retry value will be set as the Retry-After HTTP header's value::
php artisan down --message='Upgrading Database' --retry=60
To disable maintenance mode, use the up command::
php artisan up
