Building a Distributed DNS Server in a Week with AI: Zero Incidents
davidcrawshaw · x · 2026-07-21
A developer shared a case study of using AI to build a distributed DNS server in approximately one week. The project underwent two intentional rebuilds and shipped successfully, allowing the author to go on vacation immediately with zero incidents in the following month.
The author emphasizes that achieving this stability wasn't about blindly relying on "vibe-coding," but rather maintaining rigorous engineering discipline.
