After a hiatus of several years, the traditional CESNET e-Infrastructure Conference is returning. This year also marks the 30th anniversary of the association’s founding, making its return more timely than ever. We therefore invite you to the Diplomat Hotel in Prague on September 30 and October 1 for a two-day event dedicated to technologies, services, and research for science, research, and education. We will present the latest developments in the world of networks, cybersecurity, data storage, and high-performance computing. You can also look forward to the results of research and projects we are working on at CESNET, as well as our popular technology demos.

The first day will be dedicated to news, projects, and trends across e-infrastructure. The second day will feature thematic sessions focused on computing infrastructure and data storage, cybersecurity, multimedia, and research. The program will also include a Phishingator workshop and expert consultations with the Data Storage Department.

Registration is now open. You can register until September 18, 2026, or until capacity is reached.

 

This year’s IPv6 Day conference is now over. If you were unable to attend in person or would like to review any of the presentations, you can now find video recordings of all the talks and the presentations in PDF format on the conference website.

The conference took place on June 4, 2026, at the National Technical Library in Prague and, as usual, provided a forum for sharing experiences in the fields of IPv6, modern networks, and Internet infrastructure. Experts discussed topics such as the implementation of IPv6 in government, the use of IPv6 in grid computing environments for CERN experiments, and the question of whether and how cyberattackers exploit IPv6. If any of these topics piqued your interest, now is the perfect opportunity to revisit them.

IPv6 Day is jointly organized by CESNET, CZ.NIC, and NIX.CZ.

The annual IPv6 Day conference is fast approaching. On June 4, the National Technical Library in Prague will host the latest edition of this event focused on the IPv6 protocol, modern networks, and the future of Internet infrastructure. The full program is now available on the conference website, and registration is open.

You can look forward to a full day of expert presentations offering insights into the current state of IPv6 development in the Czech Republic and around the world. You will learn, for example, how the implementation of IPv6 is progressing in the public sector, how IPv6 works in the CERN experimental grid, and whether cyberattackers are already commonly using IPv6. There will also be plenty of other news and practical insights.

Participation in the conference requires a nominal registration fee of 242 CZK. Registration and the complete program can be found on the event website.

The conference is jointly organized by CESNET, CZ.NIC, and NIX.CZ.

Zatímco v běžném životě si vystačíme s minutami nebo sekundami, v digitální infrastruktuře hrají roli nanosekundy. Bez přesného času by nebylo možné zajistit spolehlivý provoz sítí, datových center ani bezpečnostních systémů –a přesto ho většinou vůbec neřešíme.

Přenos přesného času a jeho význam patřily k hlavním tématům Průmyslového dne, který uspořádalo sdružení CESNET společně se společností PEI-Genesis. Akce proběhla 28. dubna 2026 v Domě armády Praha a setkala odborníky z výzkumu i praxe – od akademických institucí přes technologické firmy až po zástupce bezpečnostních složek.

Demonstrates real-world viability of quantum encryption without performance tradeoffs They demonstrated the practical feasibility of quantum encryption without compromising performance   The CESNET consortium, in collaboration with Ribbon Communications Inc., has successfully tested the deployment of quantum key distribution (QKD) in a real-world optical network. The test confirmed that quantum encryption can be integrated into existing infrastructure without impacting its performance, paving the way for its practical use in both academic and commercial environments. “Our m

On March 6 of this year, the CESNET Association marked the 30th anniversary of its founding. To commemorate this milestone, an exhibition is currently on display at the National Technical Museum in Prague, tracing the journey from the first internet connection to today’s infrastructure for science, research, and education.

What began as an academic initiative has gradually evolved into an environment that today connects nearly 250 institutions across the Czech Republic. CESNET enables collaboration among research teams, work with large volumes of data, and the use of demanding computing and networking services that individual organizations would find difficult to provide on their own.

You can visit the exhibition on the second floor of the museum foyer through May 5. Across 21 panels, we present key moments in our history as well as our current activities. There are also specific exhibits—such as the first multiprotocol Cisco IGS router, used in December 1991 during Czechoslovakia’s historic first connection to the internet, or a 360° camera of our own design intended for broadcasting medical procedures.

The exhibition demonstrates that today’s digital infrastructure is not a given, but the result of thirty years of systematic work and development.
