This article explains why a server reboot initiated from the hosting control panel may take several minutes to complete.
This article applies to Dedicated Servers.
When a reboot action is performed via the hosting Control Panel, the power outlet connected to the server is recycled, stopping and then restoring power to the server. An automated disk integrity check will run as part of the boot process which may add several minutes on to the boot up time.
This process is an important part of maintaining the overall health of your dedicated server.
Please note: Hosting control panel reboots should only be performed in the event that remote administrative access to your dedicated server is unavailable.
