Like all our Annual Reports, the latest issue is freely available as a PDF. We will gladly send printed copies free of charge upon request.


From February to April 2024, we successively upgraded all connections of the ACOnet backbone to the global Internet (both the two Vienna upstreams and the backup upstream in Salzburg). This means we now also have a consistent bandwidth of 100 Gbps in this area, which further increases the DDoS resilience of our backbone.


GÉANT, the collaboration of European NRENs, is further expanding its security activities and is now publishing "Cybersecurity News for Academia", a monthly newsletter that focuses on IT security in the research and education sector.


We have once again summarized the main innovations of the last few months as well as some tips and hints for you in a newsletter.


Welcome to ACOnet!

ACOnet is the Austrian National Research and Education Network (NREN) for science, research, education, art and culture. It is operated by the Vienna University Computer Center, in co-operation with other universities in Austria.

ACOnet provides a nation-wide fibre optic backbone with high-performance access to international academic networks via GÉANT, as well as to the Internet. Furthermore, ACOnet offers its members various target-group-specific services to support research projects and communities.

ACOnet and COVID-19:

The ACOnet team is working from the home office again since 19 November 2021. Our availability has not changed, however. You can reach us Monday to Friday, 9:00 to 17:00, CEST; preferably by e-mail but also by phone (see contact information). In the case of an emergency you may also call us outside our office hours and leave a message. If necessary, we will call back swiftly.

ACOnet now has a 100G backbone

The technological renewal of our backbone network, which had been prepared over several years, and the additional ACOnet Point of Presence (PoP) Eisenstadt 2 were completed on schedule and without operational interruption in the summer of 2023. The last open issue, the new PoP Vienna 10, was finalized in December 2023. This means we once again have a future-proof, flexibly expandable network infrastructure. Moreover, 100G participant connections are now possible at all major ACOnet PoPs (Graz, Innsbruck, Klagenfurt, Linz, Salzburg, Vienna).
