DNS is one of the most notoriously cumbersome systems around, even for advanced engineers. Most people spend very little time (less than 1 hour per year) dealing with it, which isn't not long or often enough to commit learning to long-term memory, and the opacity of the different layers, plus tiers of caching, make it difficult to diagnose and debug problems when they arise. Even professional network engineers frequently trip over "basic" problems with DNS. It's a system with virtually zero guardrails and so many potential hazards that it's completely understandable for almost anyone to find themselves in these situation. There's a reason this haiku is so famous: > It’s not DNS > There’s no way it’s DNS > It was DNS
