We just published the "Sanctions and the Internet" report. This report was commissioned by RIPE NCC and it looked at the effect of sanctions on Internet development and access at the infrastructure level. 

Here is the link: https://digitalmedusa.org/wp-content/uploads/2023/05/SanctionsandtheInternet-DigitalMedusa.pdf

In the next few months, Digital Medusa will try to expand on the report and discuss it with various communities. So if you have feedback or suggestions on any aspect of the report, please let me know. 

Best regards,
