Our history

Founded in 2000, the Restena Foundation has its origins in a project launched 11 years earlier, even before Luxembourg was connected to the internet, which quickly allowed educational and research employees in Luxembourg to benefit from a high-performance, dedicated international connection.

Our timeline


1989: RESTENA project launched by the Ministry of Education to meet the communication needs of education and scientific research institutions in the country. Restena Office Picture
1990: Commissioning of the first network server allowing researchers to benefit from national and international connections (X.400).
1991: Integration of the RESTENA network into the X.400 research network infrastructure.
