Availability differs per location and plan. Create Server shows the images offered for the location and plan you select.

Choosing an Image

On Create Server, pick the location and plan first; the OS list updates to match.
Windows Server needs a plan with 2 or more vCPUs.
Your server page’s How to connect panel shows the exact username and port.

Logging In

Linux: sign in as the login user above, then use sudo for admin tasks.
- With an SSH key, sign in with that key.
- Without one, the password is in your deploy email.
Windows: sign in as Administrator with the password from your deploy email.

Changing the OS

Go to your server’s Settings tab, then Danger Zone → Reinstall Operating System. Reinstalling erases the disk and installs the image you choose. The images offered are the ones available for the server’s location and plan.

API

To list images and their IDs, see Images in the API Reference.
