OONI has been monitoring internet censorship around the world since 2012
What OONI does
OONI develops free software tests designed to examine the following:
- Blocking of websites
- Blocking of instant messaging apps
- Blocking of Tor and other circumvention tools
- Detection of systems that could be responsible for censorship and/or surveillance
There are risks. Running a probe involves testing connections to websites that may be banned and using tools to attempt circumventing web censorship. It is not designed to protect the privacy of those running probes. Measurements are published and can include IP addresses or other identifying information.
How OONI Works
OONI scans TCP, DNS, HTTP and TLS connections for tampering. Some tests work by requesting data over an unencrypted connection and comparing against a known good value. Others check for DNS spoofing, keyword filtering, transparent proxying and website block lists.
