Rebooting your VPS is quite simple. However, there are a couple of things that you need to know / do. Please find the outlined below:

• Locate your welcome email (within the welcome email you will find the root username / password).
• Go to https://your-ip-address:4643 (Please replace "your-ip-address" with your ACTUAL IP Address).
• You now will receive a security warning saying "this certificate is self-signed", please accept this and continue.
• You will be prompted to login, please input all the login info that you obtained in the welcome email.
• Once logged in, you will see "Reboot" at the top of the page, and you will be able to restart your VPS.

That should do it, simply follow the above guidelines, and your VPS will be restarted!
