Resilience is Ukraine












NOG Meetings are the heartbeat of a local community! When on February 24, 2022, the armed forces of Russia carried out a full-scale invasion of Ukraine destroyed communication infrastructures that are elementary for communication and were at that time. Since the invasion, we have seen network operators from whole world working together and pursuing a common goal: "Keep Ukraine connected!" Now is the time to get everyone involved around the table and talk about what happened, show projects to present realized restorations! The aim is to share experiences, to unite local technical specialists, to integrate the Ukrainian community into the international one in order to become even stronger together.
NOGUA - Network Operators Group was born in Ukraine and first successful meeting was held in 2024! We believe that NOGUA meetings will become our annual tradition, so we are very pleased to invite you to the second NOGUA conference, which will take place from November 13 to 16, 2025!
Registration is open!

The experience of international backbone operator RETN
The world has become fragile, uncertain and unpredictable.
How can we remain resilient when systems collapse instantly and stability is a myth?
Using RETN's experience as an example, we will look at how telecom companies build anti-fragile networks — from geographic diversification and zero-trust models to cyber resilience, hybrid clouds and human leadership.
In the BANI world, it is not those who avoid chaos who win, but those who know how to turn it into innovation.
Speaker: Olena Lutsenko, Business Development Director at RETN Group
The resilience of Ukrainian communications at the level of backbone networks, data centres, traffic exchange points, cloud services and local ISPs during the war.

Presentation of documented experience in maintaining the stability of Ukrainian networks during the war.
The BCOP (Best Current Operational Practices) Task Force was formed at RIPE 67 in October 2013 to initiate and coordinate the process of documenting important common operational practices in the field of Internet networks. Since the start of the full-scale invasion, RIPE has been carefully studying the unique experience of Ukrainian operators and, based on NOGUA, already has good practices that form the basis of documented network resilience recommendations for the entire global community.

Ukrainian telecom has become the target of thousands of cyberattacks — from massive DDoS to multi-level penetrations into critical infrastructure nodes. The years 2024–2025 have brought us new challenges, but also formed new practices — mandatory for implementation for every telecommunications operator, data center or cloud service. Among us are operators, providers, representatives of IXPs, government agencies and the international community. Each of you is an important link in joint cyber defense.
Questions for discussion:
- What are the new threats to cyberspace?
- How are Ukrainian operators adapting to them?
- Are we forming a single cyberspace with the EU and what can we learn from each other?
- How to build resilience through cooperation?

IPv6 is not just an ‘updated IPv4’, but a fundamentally different approach to network architecture.
It is often described as ‘IPv4 on steroids,’ but in reality, IPv6 opens up possibilities that the old protocol will never have — from multicast and autonomous device operation to flexible next-generation routing mechanisms.
Practical examples of where IPv4 limits development and how IPv6 solves these problems.
Speaker: Oleksiy Semenyaka, Senior Community Development Officer, Technical Advisor of RIPE NCC
