Blocking and filtering
Websites, apps or whole protocols are made unreachable by DNS tampering, IP blocking or deep packet inspection.
Free expression and equal access are two sides of the same right. This page is about both: resisting censorship, and building a web that works for every person, on every device, including the ones that don’t exist yet.
It is rarely a single dramatic switch. Most of the time it is quiet, technical and easy to miss, which is why it works.
Websites, apps or whole protocols are made unreachable by DNS tampering, IP blocking or deep packet inspection.
Connections are slowed until video and messaging are useless, or the network is cut entirely during protests and elections.
Platforms are pushed to delete lawful speech. Journalists, researchers and activists face legal threats and harassment.
When people believe they are watched, they stop speaking. The chilling effect is censorship without a single block.
No tool is a magic shield, and none replaces local legal and safety advice. But these are widely used, open and well reviewed starting points.
DNS over HTTPS or TLS stops simple DNS-level blocking and keeps your lookups private from your network.
Tor routes traffic through several relays. Bridges and pluggable transports help where Tor itself is blocked.
Use messengers where only the sender and recipient can read messages, and enable disappearing messages when it matters.
Publishers can keep mirrors, offer a Tor onion address, and archive their work so one takedown is not the end of it.
Projects such as OONI let volunteers test and publicly document what is blocked, and where.
Strong unique passwords, a password manager, two-factor authentication and timely updates stop most real-world attacks.
A page that someone cannot read, hear, navigate or afford to load is a page that is censored by design. Accessibility is part of online freedom.
Every new interface can include people or leave them out. Aim to include them from day one.
AI can lower barriers with captions, summaries and translation, but it can also introduce biased filters and opaque moderation. Automated systems should be transparent, contestable and tested with disabled users, not only for them.
