iMAP Myanmar 2023 Internet Censorship Report | Page 57 When blocking is determined, any domain redirected to these IP addresses would be marked as “dns.confirmed”. Secondly, HTTP titles and bodies were analysed to determine blockpages. This example shows that the HTTP returns the text “The URL has been blocked as per the instructions of the DoT in compliance to the orders of Court of Law”. Any domain redirected to these HTTP titles and bodies would be marked as “http.confirmed”. As a result, false positives are eliminated and more confirmed blockings are obtained. In the 2022 report, only confirmed blockings based on OONI or new fingerprints were reported. For this round of reporting in 2023, we further identified confirmed blockings by verifying blockings shown in news reports with OONI measurements. This is because there were blockings that could not be identified using the DNS or HTTP fingerprints. Typically, these websites were redirected to an unknown or bogon IP address, or they had other unknown errors that are ambiguous as to whether they are true or false positives of censorship. Hence, based on the news reports where the blocked websites were cited, confirmed blockings were further found by comparing available measurements on OONI.For this study, we marked them as confirmed blockings if there are more than 30 measurements and an anomaly rate of more than 1% throughout the one-year period of study. In addition, we manually checked the OONI measurements by cross-checking across networks, countries and time periods.
