Unable to access website bc server not responding

Hi all,
I’m trying to access my website but I get a message the page cannot be opened because the server where it is located is not responding.
I don’t deal with any of these and my developers are the ones who look after it but they’re currently unavailable and trying to get my head around it myself.
Any idea what the issue could be?

what is the site example dot com is a good start
