Revisit of the Domain Name System After Russia's Invasion of Ukraine [March 23, 2022] [open pdf - 747KB]
From the Document: "Following Russia's invasion of Ukraine in February 2022, Ukrainian Deputy Prime Minister Mykhailo Fedorov asked [hyperlink] the Internet Corporation for Assigned Names and Numbers (ICANN) to sanction Russia's internet access. Federov requested changes to the domain name system (DNS) [hyperlink]--revoking the top-level domains '.ru,' '.pф,' and '.su' and shutting down four DNS root servers located in Russia--to 'help users seek for reliable information in alternative domain zones.' ICANN responded [hyperlink] that (1) ICANN does not 'take unilateral action to disconnect' domains, and (2) independent operators maintain the geographically distributed DNS root server system. Further, ICANN stated it has neither the authority nor ability to impose sanctions as it 'does not control internet access or content.' Days after ICANN turned down Ukraine's request, two top-tier U.S.-based internet service providers terminated [hyperlink] their services in Russia. In an open letter [hyperlink] to the Biden Administration, 41 civil society organizations that advocate for digital rights cautioned against sanctions that would disrupt internet access for Russian users and inhibit their ability to access factual information and organize opposition to the war."
