9/24/21, 8:39 PM The State of Internet Censorship in Myanmar | OONI OONI by default collects the code which corresponds to the country from which the user is running OONI Probe tests from, by automatically searching for it based on the user’s IP address through the MaxMind GeoIP database. The collection of country codes is an important part of OONI’s research, as it enables OONI to map out global network measurements and to identify where network interferences take place. Autonomous System Number (ASN) OONI by default collects the Autonomous System Number (ASN) which corresponds to the network that a user is running OONI Probe tests from. The collection of the ASN is useful to OONI’s research because it reveals the specific network provider (such as Vodafone) of a user. Such information can increase transparency in regards to which network providers are implementing censorship or other forms of network interference. Date and time of measurements OONI by default collects the time and date of when tests were run. This information helps OONI evaluate when network interferences occur and to compare them across time. IP addresses and other information OONI does not deliberately collect or store users’ IP addresses. In fact, OONI takes measures to remove users’ IP addresses from the collected measurements, to protect its users from potential risks. However, OONI might unintentionally collect users’ IP addresses and other potentially personallyidentifiable information, if such information is included in the HTTP headers or other metadata of measurements. This, for example, can occur if the tested websites include tracking technologies or custom content based on a user’s network location. Network measurements The types of network measurements that OONI collects depend on the types of tests that are run. Specifications about each OONI test can be viewed through its git repository, and details about what collected network measurements entail can be viewed through OONI Explorer or through OONI’s measurement API. OONI processes the above types of data with the aim of deriving meaning from the collected measurements and, specifically, in an attempt to answer the following types of questions: Which types of OONI tests were run? In which countries were those tests run? In which networks were those tests run? When were tests run? What types of network interference occurred? In which countries did network interference occur? In which networks did network interference occur? When did network interference occur? https://ooni.org/post/myanmar-report/ 15/19
