MANRS Development Process Proposal: Review of the Network Operators Program
by Nick Hilliard (INEX) May 21, 2026

May 21, 2026

Dear MANRS Community, Following the recently published community survey on the future of the MANRS Actions, the Steering Committee is pleased to announce the initiation of the MANRS Development Process (MDP) to review the MANRS Network Operators Program. As part of this process, we are forming a dedicated MANRS Network Operators Program Review Working Group (NetOpsRev WG) to assess and evolve the MANRS Actions in line with community feedback and the evolving routing security landscape. Participation in the Working Group is open to all interested individuals, including network operators, security experts, researchers, and other stakeholders. You do not need to be a current MANRS participant to join. A draft charter is available <https://manrs.org/about/network-operators-program-review-working-group/>, and the group’s first task will be to review, revise, and finalize it. We invite you to contribute your expertise to this important effort. If you are interested in participating, please contact the MANRS Secretariat by email at secretariat(a)manrs.org before May 1, 2026, providing a brief background about yourself, your current role, and relevant experience or interest in routing security. We look forward to your engagement in shaping the next evolution of MANRS. You can find the full MDP proposal here: * Proposal URL: https://manrs.org/proposals/19444/ * Proposal Name: Review of the Network Operators Program * Specification Type: Normative * Proposal Type: Update Best regards, MANRS Steering Committee

BGP Stuck Routes Operational Experience Survey
by ixygkou3＠gatech.edu April 16, 2026

April 16, 2026

Dear MANRS 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phenomenon of BGP stuck routes (also known as "zombie routes")—prefixes that persist in routing tables despite being withdrawn by their origin AS.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".
