Is there a false alert prevention feature with WebSitePulse?
If an error is detected the monitoring agent tries to confirm it with a secondary location. The secondary location performs the same tests as the primary location and sends the result back to the monitoring agent. If there was a problem connecting to the secondary location the confirmation procedure is repeated with a third location and if the error is not confirmed or both second and third location are unreachable the monitoring agent will record a successful test. Currently you cannot change the locations that are used to confirm the error.
