A Down problem indicates that the application is not responding to connection requests to any of its ports.

To diagnose Down in this scenario, Application Connectivity Monitor must observe that all TCP checks to both TCP ports in use by HTTPService time out, causing TimedOutSymptom events. The TimedOutSymptom events indicate that the Web server is not responding to connection requests.
