The VPS’s are fully Managed. But they only manage what they install. For example, if you order a VPS with no control panel they only manage the operating system. They will support any operating system related problems you may run into. Such as boot-up issues, security updates, patches, reinstalls, and so on. If your server is purchased with a control panel such as cPanel, InterServer will support any software that is installed by the control panel. Such as the control panel itself, web server, FTP, mail, and so on. InterServer will not support any 3rd party software such as blogs, scripts, and forums.
