BGP Stuck Routes Operational Experience Survey
by Xygkou, Iliana M 07 Apr '26

07 Apr '26

Dear RIPE community members, We are researchers from Georgia Tech investigating the phenomenon of BGP stuck routes (also known as "zombie routes")—prefixes that persist in routing tables despite being withdrawn by their origin AS. While recent research using BGP beacons (including our work presented at IMC 2025 [1]) confirms that zombie routes occur regularly and can persist for long periods, there is a gap in understanding the operational reality of this issue. We observe the data, but we need to hear from operators to understand the real-world impact and their mitigation responses. We invite you to participate in a brief, anonymous survey to help us assess the extent and impact of this phenomenon in operational settings and to identify common practices for mitigating it. Survey Link: https://forms.office.com/r/9BuWqN0n0J Privacy & Data Usage: This survey is anonymous. We are not collecting any PII (Personally Identifiable Information) data. Thank you for your time and for your contributions to this Internet measurement study. [1] I. Xygkou, A. Chariton, X. Dimitropoulos, and A. Dainotti. "A First Look into Long-lived BGP Zombies".

Felipe Victolla Silveira Leaving the RIPE NCC
by Hans Petter Holen 07 Apr '26

07 Apr '26

Dear colleagues, I would like to inform you that after 13 years at the RIPE NCC, Felipe Victolla Silveira is stepping down as CTO and will be leaving the RIPE NCC. Felipe has made a significant contribution to the organisation over the years, holding a number of key roles. Starting in 2012 as a Software Engineer, Felipe then became Software Engineering Manager before joining our Executive Team as Chief Operations Officer with responsibility for the Registry and our Business Applications, including the LIR Portal. Notably, Felipe served as Interim Managing Director from October 2019 to May 2020, ensuring stability through the leadership transition from Axel Pawlik to me. For the past three years, Felipe has further contributed to the development of the RIPE NCC and the resilience of our core services in the role of Chief Technology Officer. During his time with us, Felipe played an important role in shaping both our technical direction and organisational development. His achievements include leading the modernisation of our ticketing system and the phase-out of XRTT, and implementing automation that accelerated the overhaul of our sanctions compliance processes. Felipe also worked closely with the community to define our service criticality and how that should lead to the use of third-party services, continually revisiting that decision in light of changing external factors and community input. He contributed to our achieving ISAE 3000 / SOC 2 compliance for RPKI, and during his tenure, we strengthened the high availability and resiliency of RPKI services. We also modernised the RIPE Atlas infrastructure, including the Hadoop cluster migration to Hetzner. We are grateful for Felipe’s dedication, leadership and the lasting impact of his work across the organisation and the community. We wish him all the best in his future endeavours. Kind regards, Hans Petter Holen Managing Director and CEO RIPE NCC
