I am using a third party service for a contact form. Multiple people have reported that the form is not loading. At my work the form does not load either. In the console I can see I am getting an ERR_CONNECTION_RESET for one of the JS files from the third party. In my browser I can navigate to that file directly and it loads just fine.

Is there a way in javascript to know if this happens so that I can display a message for my viewers?
