What actually happens in the 1.2 seconds after you type a URL and hit Enter?

What actually happens in the 1.2 seconds after you type a URL and hit Enter? I built a website that shows you in 3D! One request, from your keyboard to any URL and back: → DNS lookup, all the way to the authoritative nameserver → TCP handshake → across the undersea cables (on a cache miss to a US origin) → Vercel's edge → HTML back, parsed, painted on your screen The DNS answer, IP and nameservers are real records, not placeholders. Built with @claudeai Opus 5.5 + Three.js. The video itself is rendered frame by frame on a virtual clock in headless Chrome and piped into ffmpeg, so it plays perfectly smooth no matter how slow each frame was to render. Every dev gets asked this in an interview at some point. Now you can just send them this. Live: Code:
