We offer popular Linux distributions and Windows Server, including:
- Linux: Ubuntu, Debian, AlmaLinux, Rocky Linux and other distributions.
- Windows Server: bring your own licence. You must supply a valid Windows Server licence that allows use on hosted infrastructure. We may run read-only checks of the licence and activation status.
The current list of versions is shown when you order a VPS and on the Reinstall OS page of your VPS. You can reinstall or change the operating system there at any time. Reinstalling erases the server's disk, so back up first.
The same page also lets you mount an ISO from our list. See section 3 of the Terms of Service for Windows licensing.
