Dear colleagues, A quick reminder that our online Data Sovereignty seminar series will take place on 13 December at 15.00 (CET) with Ksenia Ermoshina (CIS-CNRS) on the project of the sovereign Russian internet in the context of the ongoing war and economic sanctions. Registration: https://brussels-school.be/event/data-sovereignty-seminar-5sanctions-war-and... While the Russian authorities have been tightening their control over RuNet for the last decade, there have been multiple possibilities for circumvention and evasion both for the RuNet users and for Internet Service Providers. We have previously examined the dynamic relations between the ISP community and the regulators, and described various tools and practices used by ISPs to avoid total control over the networks. However, with the adoption of the law on "Sovereign Runet" in 2019, Roskomnadzor hardened its grip over the networks. The new generation of DPI middleboxes called "TSPU", officially "made in Russia", changed the way RuNet was filtered and left little to no chance for ISPs to boycott censorship and surveillance over their users. However, after the beginning of the full-scale invasion of Ukraine by the Russian Federation, the technological sovereignty project was challenged — on the very level of infrastructures. Sanctions of technological companies against Russia led to a crisis of both components and software solutions, revealing a profound dependency of the RuNet on foreign technologies. The presentation will explore the effects of sanctions on the project of the Sovereign Runet, based on a mixed-methods approach: interviews with ISPs and vendors of information control equipment, analysis of vendors' websites and technical documentation of the equipment, analysis of websites and materials of specialized exhibitions focused on cybersecurity equipment and finally, network measurements.
