In this episode, host João Tomé talks with Marwan Fayed, Principal Scientist and Research Lead at Cloudflare, about the science behind understanding and improving the Internet.

They explore the Research Week blog takeover on Measurement, Resilience, and Transparency, discussing the tricky science of Internet measurement — including a traffic spike in Ukraine that revealed how complex it is to explain data at scale. Marwan shares how Cloudflare is building a framework for Internet resilience, preparing for a post-quantum future with Merkle tree certificates, and tackling the “store now, decrypt later” risk. They also cover Cloudflare’s work to identify users behind Carrier-Grade NAT, innovations in protocol defense, anonymous credentials, and the story behind WARP VPN.

At the heart of it all: how to make the Internet safer, faster, and more transparent, at global scale.
