KOSIX started operating in mid-2011 as a functional unit within the Telecommunications Regulatory Authority (TRA) and is housed at the University of Pristina’s Electrical and Computer Engineering Faculty. The project to develop the exchange was supported by the United States Agency for International Development (USAID), the Norwegian Government's Ministry of Foreign Affairs and Norwegian embassy, and Cisco Systems.

KOSIX currently has 4 members exchanging about 60Mbps of peak traffic. Of note is that the KOSIX website is keen to promote the data sovereignty benefits of the exchange: “[t]he advantages offered by KOSIX are many, one of the most important being the advancement of security and privacy of communication on the Internet, keeping the local traffic ‘local’ within national borders, without leaving the national boundaries as it has previously been prior to the function of KOSIX. This reduces the risk component when sending sensitive data across national borders and through many exchange points.”
