The server status checker tool allows you to see what response/status code the web server is returning when the user is requesting the page. It also enables you to check the website status i.e. is the site reachable or not.
If the server is not working, users won't be able to access the websites. This will affect the revenue or the earnings.
A web server may return status code of various type. If it is running and the configuration is correct, you'll see HTTP status 200 or 404.
If there's configuration error, the web server will return HTTP status code 503.
If the server is not reachable, the tool will display the following message "Could not connect to the URL which means the server is either down or there's no website named URL". If the page is reachable, you'll see the page's HTTP status code.
