Censored Planet is a censorship measurement platform that collects data using multiple remote measurement techniques in more than 200 countries.

The website provides access to many recent scans. The scans are performed using different techniques to find different censors.

The GitHub repository contains multiple lists for finding website censorship. The lists are organized by country and contain URLs specific to each of them. The URLs are also categorized and cover four broad themes:

• Political, e.g., governmental views or human rights
• Social, e.g., sexuality or gambling
• Conflicts, e.g., armed conflicts or border disputes
• Internet tools, e.g., hosting providers or circumvention methods.

The ICLab data provides longitudinal access for censorship data. The data is collected from 2016 onwards. The analysis encompasses different censorship techniques such as DNS manipulation or packet injection.

Open Observatory of Network Interference (OONI) is an active measurement platform for censorship measurements. Many different measurements are run, such as blocking of messengers, Tor and VPN blocking, or middle boxes.
