Coursera, a US-based online education company, announced on 28 January 2013 that US sanctions laws and regulations prevented it from offering its online courses to students based in Cuba, Iran or Sudan. US officials have not commented on the matter, although Coursera has stated that it is working closely with the US Department of State and OFAC “to secure permissions to reinstate site access for students in sanctioned countries.” Coursera previously believed that the services it offered online were not covered by US export controls but had recently received information that caused it to conclude otherwise, prompting the company to implement a system that blocks access to users with IP addresses located in the sanctioned countries. Coursera had initially blocked access from Syria as well, but later unblocked Syria in reliance on OFAC’s General License No. 11A.
