OONI
The Open Observatory of Network Interference is a project that monitors internet censorship globally. It relies on volunteers to run software that detects blocking and reports the findings to the organization. As of June 2023, OONI has analyzed 1,468.4 million network connections in 241 countries.
Development
OONI was officially launched in 2012 as a free software project under The Tor Project, aiming to study and showcase global internet censorship. In 2017, OONI launched OONI Probe, a mobile app that runs a series of network measurements. These measurements detects blocked websites, apps, and other tools in addition to the presence of middleboxes. Results of these tests can be utilized through the OONI Explorer and API.Till 2018 the project received $1,286,070 of funding from the Open Technology Fund.
