Don't Touch It

That dusty D-Link switch held together by what appears to be sticks, twigs, and sheer willpower is basically every production network switch that's been running flawlessly for 15 years. Nobody knows why it works. Nobody knows who configured it. The documentation? Lost to time. But the moment you even think about replacing it or updating the firmware, the entire network will collapse like a house of cards.

It's held up by literal branches in what looks like an abandoned barn, covered in dust and cobwebs, yet somehow it's still blinking those reassuring green LEDs. Touch it and you'll spend the next 72 hours explaining to management why the entire company lost internet access. Some infrastructure is best left as a monument to "if it ain't broke, don't fix it."
