Cloudflare has launched support for DoT and DoH for its resolver from day 1. With DNS traditionally carried over UDP, moving to connection-based and encrypted transport protocols brings new operational challenges. This talk will cover the protocol uptake, deployment challenges with both protocols, as well as the feasibility and overhead for providing the service. It will show the evolution of our current system architecture, and client-side software.

Talk Duration 30 Minutes
