Episode Details

A wrong AC adapter sent 52 volts into a 12-volt fiber modem, and the sizzle lasted a second and a half. That accident opens a bigger question: how do you decide which spares to stock when you can't afford to hold one of everything? This episode walks through the three-tier stocking model that managed service providers actually use, what the homelab resilience literature recommends, and how PJM — the largest wholesale electricity market in North America — thinks about spare equipment for the bulk electric grid. Along the way: why the cheapest component in your network is usually the one that dies, why a used-but-unreplaced spare is worse than no spare at all, and why "single node, move the drive" is a legitimate strategy that optimizes for something completely different.
