A LumaDock VPS keeps running until something stops it: a power action, a reinstall, an unpaid invoice, maintenance or a hardware fault. You can check most of these yourself in the client area.
What to check if your VPS is down
Step 1: Check for an unpaid invoice.
A server is suspended when its renewal invoice stays unpaid. If you see an unpaid invoice under Financial > My Invoices, pay it, and the server is switched back on automatically. The details are in What happens if a payment fails.
Step 2: Start the server.
On the server's page, click Start under Service Actions if the server is stopped.
Step 3: Check Task History.
Under Service Management, Task History lists the power actions and reinstalls run from the client area.
Step 4: Look at the server's screen.
Open noVNC Console under Service Management. If you see a login prompt, the server is running, and the problem is inside it, for example a service that stopped or a firewall rule.
Planned maintenance and restarts
We usually announce planned maintenance by email, and sometimes with a banner in the client area. A hardware fault can restart a server without notice.
To see when a Linux server last started, run uptime -s in noVNC Console or over SSH.
Keeping services running after a reboot
A reboot stops every running program. Set your programs to start when the server starts:
sudo systemctl enable nginx
For Docker containers, use a restart policy:
docker update --restart unless-stopped CONTAINER
Getting an email when your server is down
Server Monitoring, under Service Management, checks your server and emails you a Server check alert when a check fails.
Click Create Check, choose a check type, for example Port Connect on port 22, and choose your email under Notification Recipients.
