OONI has confirmed data analyzing the 2019 Internet blackout in Iran.[10] On 24 February 2019, Cuban independent news outlet Tremenda Nota confirmed the blocking of its website a few hours before a referendum in Cuba. A new Constitution was voted in the country for the first time in decades. OONI network measurement data confirmed the blocking of the site along with several other independent media websites during the referendum.[11] The network had previously confirmed 41 websites blocked in the country in 2017.[12][13] Cases of internet censorship and network disruptions during elections have also been detected in Benin,[14] Zambia,[15] and Togo.[16] In May 2019, OONI reported that the Chinese Government blocked all language editions of Wikipedia.[17][18] Following the 2022 Russian invasion of Ukraine, OONI confirmed that most Russian Internet Service Providers started blocking access to Twitter, Facebook, Instagram, BBC, Deutsche Welle, Radio Free Europe, Voice of America, Interfax, Meduza, Dozhd, The New Times and 200rf (a website launched by the Ministry of Internal Affairs of Ukraine to enable Russians to find their family members who were captured or killed during the war).[19]
