This podcast series examines how internet censorship shapes global access to information and the technical safeguards needed to ensure a free and open web. We dive into the mechanics of filtering, circumvention strategies, and the role of internet protocols in protecting privacy, security, and freedom of expression. Voice and scripts by NotebookLM with input from Nick Sullivan and published research.

In this season finale, we explore how encryption and obfuscation tools are adapting to advanced censorship. Topics include potential client-side backdoors, the centralization of encrypted services, and the role of grassr
MASQUE (sometimes spelled “mask”) expands on HTTPS-based tunneling to conceal additional traffic types, including IP-level tunnels. You’ll look at how MASQUE can make censorship more difficult by blending various protoco
TLS used to expose data like Server Name Indication during the handshake. Encrypted Client Hello (ECH) fixes that by encrypting handshake info, defeating SNI-based blocking. This episode covers how ECH works, its adoptio
Shifting into the encryption era, you introduce DNS over HTTPS (DoH) and explain how it attempts to shield DNS queries from on-path observers. This episode investigates the controversies around DoH—whether centralization
This episode explores how DNS, traditionally in plaintext, exposes user intentions and becomes a target for censorship via spoofing, redirection, or injection. It covers classic DNS-based blocking tactics and examines ho
Here, you map out the “where” of censorship: ISPs, internet exchange points (IXPs), backbone providers, and government-run or regulated network segments. The focus is on how each actor can enforce blocking or filtering,
This episode explores how unencrypted (plaintext) traffic historically enabled governments, ISPs, and entities to monitor and control internet communications. You'll learn foundational concepts—such as internet structure
How do people in censored environments access information? We explore user perspectives, priorities, and barriers to using circumvention tools. Research from Xue et al. highlights challenges in trust, funding, and usabil
Some governments take censorship further by shutting down the internet entirely. We analyze case studies from Myanmar, Ethiopia, and Sudan, examining economic and social impacts, resistance strategies, and expert insight
We examine popular circumvention methods—VPNs, Tor, and encrypted DNS (DoH/DoT)—and how governments counter them. What makes these tools effective? What are their limitations? Insights from Feldstein reveal the ongoing b
Censorship isn’t just about blocking—sometimes, it’s about disruption. This episode covers DDoS attacks, how states and non-state actors deploy them, and their impact on independent media. We discuss mitigation technique
We dive into Deep Packet Inspection (DPI), TCP resets, and packet filtering—tools used to inspect and block content. As HTTPS adoption grows, how does it challenge censorship? We examine how encrypted protocols make DPI
We explore early censorship techniques like IP blocking and DNS manipulation, alongside economic levers such as data taxes and ISP restrictions. How did these methods evolve, and how effective were early circumvention st
This episode introduces internet censorship, exploring its motivations—political, economic, and cultural. We discuss its impact on societies and individuals, the tools governments use, and a preview of future episodes on
