I recently experienced a power cut which brought up a few issues and it would be great if Cortex could warn of. Firstly my internet router had a hiccup on restart and cortex helpfully informed me it could not connect to to the internet through the "On public IP address seek error" which was a good indicator. The main issue I had however is I have a NAS setup for IP cameras and this did not reboot and therefore the cameras were not recording events for some time. If cortex could ping local IPs in addition to the single public IP address and report on failures this would be great. Even better would be if it could attempt to write a file but a ping would probably be sufficient for most cases.
