Based on the web connectivity test results, the most used methods of censorship by ISPs are DNS blocking (dns.confirmed) and HTTP blocking (http.body.confirmed). Out of 177 websites, 123 websites (69%) are blocked with the use of DNS blocking and the 54 (31%) are blocked with HTTP blocking. The following chart illustrates the percentage of websites blocked by the two blocking methods. Figure 4: Percentage of websites blocked by different blocking methods While analysing blocked websites for the 2022 iMAP report, one limitation was the unspecified website categories that were not under the 30 categories of the CitizenLab test lists. So out of 286 blocked websites in 2022, only 112 blocked websites of 11 categories were reported in detail. However, all 286 blocked websites were annexed in the 2022 report. In the 2023 report, all of the blocked websites have been categorised according to the CitizenLab categories, some of them by the researchers manually. As mentioned above, the measurement results in this study period show that there are 177 confirmed blocked websites under 23 categories (see Annex I) with 12 new categories as below. The one website category that is common to both 2022 and 2023 reports is Public Health. 1. Alcohol & Drugs 2. Control content 3. Culture 4. E-commerce 5. Economics 6. Environment
