Internet Insights with Cloudflare Radar: New TLD Metrics, Certificate Transparency, and Data Explorer

In this second part of episode #109, host João Tomé talks with André Jesus, Systems Engineer at Cloudflare and front-end engineer on the Radar team. They discuss the latest updates to Cloudflare Radar, the platform that turns Internet data into accessible insights.

André, who joined Cloudflare as an intern in Lisbon, Portugal, in 2024, explains how radar.cloudflare.com showcases trends in Internet traffic, protocol adoption, and security. He walks us through Radar’s new Top-Level Domain (TLD) insights, how the team uses DNS magnitude to measure domain popularity, and why certificate transparency is crucial for a safer web.

The conversation also goes into outage monitoring, the Data Explorer and URL scanner tools, and how users around the world are finding surprising Internet trends — like the rise of Linux usage in France.
