The three stages of every network troubleshooting session, beautifully captured as poetry against cherry blossoms: First, the denial: "It's not DNS" Then, the stubborn resistance: "There's no way it's DNS" Finally, the crushing realization: "It was DNS" DNS (Domain Name System) is the internet's phonebook that translates human-friendly domain names into IP addresses. And somehow, despite being the first thing you're supposed to check, it's always the last thing you actually check. The haiku-like progression perfectly captures the emotional journey from confidence to despair that every network admin has experienced at 2AM while the production server is down.
