It is 11:17 PM. A single fiber degrades on an edge router, and within seconds your console lights up: an optical power alarm, two interfaces down, a service outage, and a traffic spike on the neighboring link that just absorbed the rerouted load. Five alarms, one actual problem. Multiply that [...]

An AI agent enrolled 181 nodes onto a production network over four and a half days, ran an improvised command-and-control system, and moved laterally through the org.
