Plesk-wide maintenance mode
At times it takes quite significant time to perform plesk in-place upgrade. During this time all sites are down and plesk control panel is down as well.
It would be good to have plesk-wide maintenance mode for such occasions that would display a nice maintenance or upgrade notice page that would be displayed to whoever accesses the sites hosted in plesk or plesk control panel itself.
We want a Plesk feature introduced that will let us perform scheduled maintenance. Yet, occasionally we discover whether we are backing up to our remote servers. Customers occasionally log in to the control panel. They submit a ticket to us complaining that their modifications weren't preserved. We are unable to prevent users from accessing their control panels.
Plesk Tech Support commented
Add a feature to prevent users from accessing the Plesk interface, except for administrators with an appropriate error such as "Server Maintenance". So it will be possible apply server changes without any other changes done during the maintenance.
Could you add possibility notifying customers, which using Plesk Panel at the moment, when carry out maintenance work on the server (Update, Verifying or Fixing Error etc.)?
P.S. Need for reducing requests from customers
Would be very good to have a plesk-wide maintenance mode. Only te currently logged in admin user should be able to access plesk and the others get redirected to a info page. Or others should be prevented to access plesk with firewall rules.
