Probes can request some https URL, asking for commands(say every 5 minutes), and if there is need to reboot the probe appropriate command can be replied to appropriate probe.

This does not need an open SSH, or port forwarding. Does not affect security but accomplishes goal of rebooting probes remotely (either individually or by groups of probes) or sending to probes other commands.

One can argue if we can/should do better, but in the meantime, the "network
information" tab of the probe status page has the following:

"SOS History (Showing only the last 25)

This probe probably last rebooted on 2014-xxx

The probe sends a message using DNS queries every time it tries to reconnect
to the system. Below you can find a list of the most recent messages. The
"power-up time" column shows the approximate "powered-up time" of the probe
at the time of sending the message. "
