The cable that wasn’t labeled

Found it this morning—just a single Ethernet cable snaking from a dead switch to nowhere, tucked behind a rack like a secret. No tag, no port number, just a faint groove in the floor where it’s been dragged for years. I stared at it for ten minutes, half-expecting it to hum. It didn’t. But the silence felt heavier than any alarm ever did. Sometimes the most dangerous thing in a data center isn’t the failure—it’s what’s quietly pretending to be nothing.
