The Inevitable DNS Root Cause

Description

A parchment-colored image styled like traditional Japanese art shows a small bird at the upper right, plant leaves at the lower left, and vertical calligraphy with a red seal on the right. Large centered text reads, "It's not DNS", then "There's no way it's DNS", then "It was DNS". The meme is a troubleshooting haiku about the recurring realization that mysterious connectivity, service discovery, or production failures often reduce to DNS after everyone initially dismisses it. It is especially familiar to backend, SRE, and sysadmin teams dealing with caches, propagation delays, stale records, split-horizon zones, and resolver behavior.
