A variety of internet technologies, including domain name registration services, have been declared exempt from US sanctions on Russia.
The Department of the Treasury’s Office of Foreign Assets Control has issued a notice (pdf) specifically authorizing the export to Russia for the following:
services, software, hardware, or technology incident to the exchange of communications over the internet, such as instant messaging, videoconferencing, chat and email, social networking, sharing of photos, movies, and documents, web browsing, blogging, web hosting, and domain name registration services
The move is reportedly meant to support independent media’s and activists’ fight against Russian government propaganda during the Ukrainian invasion.
Some US registrars, including Namecheap and GoDaddy, have chosen to restrict their Russian customer base on ethical grounds since the first week of the war in Ukraine.
Namecheap, which has many staff in Ukraine, has banned all Russian custom other than those actively opposing the Putin government.
