Start your VPS on a different host node using PHP and the UpCloud API.

curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_TIMEOUT, 30);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);

$array = json_decode($return, true);

// Add the current host id to avoid this one during the start request

Before you can use this script you need to enable API access via the UpCloud controle panel.

1. Change the settings for the conf.php file
2. Run the file server.php to get the host id
3. Run stop.php to stop your server (you can do that via the UpCloud panel too)
4. Edit start.php and add the host id you got before
5. Run the start.php script

I suggest to run these PHP scripts via your laptop's terminal application.
