The Power tab restarts the whole machine. It is there for emergencies; most problems are fixed faster by restarting one service.
| Action | What happens | Downtime |
|---|---|---|
| Reboot | A clean restart of the machine. Every service starts again on its own. | About a minute. |
| Shut down | A clean shutdown. Websites go offline until you press Start. | Until you start it. |
| Start | Powers the machine on if it is off. | About a minute to boot. |
Only the account owner and admins can use Power. A shut down server is still billed: the machine and its disk stay reserved for you.
Before a reboot, try restarting PHP or the one service that misbehaves (Overview, Services). It takes seconds and keeps every other site online.
