        cases where supervisor is contacted:

         1. periodic ping (health check)

         2. device connect

         3. device disconnect

         cases where failure to connect is fatal: only ping

         probe = 10 mins

         1. probe succeeds

         2. enable firewall rule

         3. device connects to websocket

         3a. device is not shown as connected in api

         3b. device attemts to subscribe to stateful supervisor (fail/retry due to firewall rule)

         4. ~3 minutes later that fails to suscribe to supervisor and device is disconncted

         4a. you'll see that failure in the logs

         5. ~7 minutes later probe starts again

         6. ~3 minutes later that probe fails to supervisor and application shutsdown

         7. remove firewall rule

         next test: add firewall rule for courier producer (ny and sg) and then try:

send a DI message

delivery report

any others?
