Keynote Red Alert's checking sequence is designed
to provide foolproof, end-to-end verification
of your device's accessibility to the Internet.
Every error condition is triple-checked
using three fully independent Internet connections
on separate backbone networks, local Internet
access providers, and local network equipment.
You are not notified about a problem unless Keynote
Red Alert has tried to reach your device on three
different paths and found it to be inaccessible
or malfunctioning on each network.
At least four times per hour, Keynote Red Alert
will attempt to open a TCP connection to your
device. If the attempt succeeds, this confirms
- Your device is running
- Your device is connected to the Internet
- Your software is listening for and accepting
connection requests on the appropriate TCP port
If the attempt fails, Keynote Red Alert will
enter a diagnostic mode in order to determine
type should be reported to you.
If the device is a Web server, Keynote Red Alert
will send an HTTP request for the URL you have
provided and checks the Web page or file returned
for other error types.
Account Summary page shows all the devices currently
being monitored for you. Links on this page enable
you to add/edit/delete your Internet devices, change
your notification options and suspend/resume monitoring
at any time.
