Quick Answer
Handle AJAX errors: $.ajax({url, error: function(xhr, status, err) { handle(err) }, timeout: 5000}). For Promises: $.ajax(opts).fail(function(xhr) { if (xhr.status === 0) alertNetworkError(); else if (xhr.status === 404) alertNotFound(); }). Timeouts fire the error callback with status "timeout" - detect this to show "slow connection" messaging vs server errors.
