subnet-sentinel watches your subnets so you don’t have to. it mounts them, tests them, and tells you the moment something stops working. if you want it to fix things or ping your alert system, just drop a script into the folder and it handles the rest. no fluff, no heavy dependencies, just a practical subnet watchdog. -alon levi from flashproxy.io
