What to do when a server is down

Question

What is the best course of action when a server is down?

Answer

If you aren't able to access a server, there are a few quick tests you can do to determine if the machine is completely offline or if there is a problem with just the websites. If pages aren't loading properly in a browser, you can try accessing WHM or cPanel using the machine's IP address to see if that allows you to access those areas of the system. If that works, the problem may be limited to just the web service on the machine. If you can't access WHM at all, you can try pinging the IP address of the server to see if it responds. You can do this from your local computer with this command:

# ping $IP

Note: Replace "$IP" with your server's primary IP address.

If that doesn't work, it's possible the machine is completely offline. In that case, you would need to speak with your hosting provider or data center to see if they can get you more details on the issue.
