    AppOffline means
    A service unavailable error occurred (an HTTP error 503). The service is not available because application errors caused the application to be taken offline.

    Do you know if your application was taken offline? Was it running?

    Make sure your website is assign to a valid app pool also.

    It could have failed and been recycled normally you should no see a drop in service here. But make sure app pool logging is turned on.

    Forgot to say also create a sepearte app pool for this site.
    and disable rapid fail protection for this app pool it could be shutting down because of failures.
