There is no way to check the server is available until you send a request to it. One way to do is to send AJAX request and see the response status. You can put this in a JS timer which will get executed at specific interval. Depending on the response status, you can show the error message.

Sorry, but this does not make sense.

A webpage is processed on the server. In order to call a page a connection must exist and then any checking code on that page would be a bit pointless.

If your client (aka browser) has no connection, then it will not be able to call the webpage and again any checking for a connection on the webpage will be pointless. The browser itself will show an error anyway when a page cannot be reached.

Relocating to an error page on the server side is just as pointless. The error page is again provided by the webserver, which, lacking a connection, cannot be reached.
