ArcGIS Mission Server has a site mode that allows you to control changes to your site. You can set the site mode to READ_ONLY to disallow the publishing of new services and block most administrative operations. Your existing services will continue to function as they did previously. Note that certain administrative operations such as adding and removing machines from a site are still available in READ_ONLY mode.

The default site mode is EDITABLE, which means all administrative and publishing operations are allowed on the site. By default, all services will be restarted when the site mode is set to READ_ONLY. Additionally, setting the site mode to READ_ONLY will copy the site configuration files to a local repository on each machine in the site. This default behaviour will enable the site to operate in a degraded capacity when there are connection failures to the configuration store.
