If you want it REALLY easy, you should be able to write a simple bash script that, when called, pings an arbitrary always online website like google, and if the ping returns an error, sends a telegram message to your phone. you could also store the current state in a separate file to allow for “is now down” and “is up again” differentiation, then use the telegram message timestamps to “track” (loosely used term) up- and downtime. To call the script, add it to your crontab and specify your test interval there.
