tangent I had a lazy fix for a down detection on my RPi server at home, it was pinging a domain I owned and if it couldn't hit that assumed it wasn't connected to a network/rebooted itself. I let the domain lapse and this RPi kept going down around 5 minutes... thought it was a power fault, then I remembered about that CRON job.
