Welcome to ACOnet!

ACOnet is the Austrian National Research and Education Network (NREN) for science, research, education, 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 complete ACOnet team is working from the home office since March 16, 2020. Our availability has not changed, however. You can reach us Monday to Friday, 9:00 to 17:00, CE(S)T; 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.

Even though our statistics show a selective increase in traffic, we do not expect any congestion within our backbone for the time being. In any case we are prepared to expand our capacities if necessary. Furthermore, it is possible to temporarily increase the overdraft limit of ACOnet participants. Organizations who are in need for higher commodity traffic bandwidth due to the current situation, please contact us at noc(at)

Stay safe, stay healthy and take care!
The ACOnet Team

Since 2013, ACOnet has been committed in the field of net:art - multi-site performances in real time via high-speed networks and specific low latency technologies. In order to promote the exchange of experience and knowledge within the community, ACOnet has also launched the net:art coordination center some time ago. Thanks to the friendly support of Kapsch, this initiative can now be presented on a new, comprehensive website.

We invite you to explore the website Take a look at the documentation of our past productions, enjoy the videos and photo galleries and follow the progress of our ambitious new project "aaron's law"!
