Survey on ASPA Validation and Enforcement in Operational Networks
by Kastanakis Savvas 05 Oct '26

05 Oct '26

Dear colleagues, We are conducting a short survey (https://forms.gle/rjmTKnjMAXe8sVmH8) on ASPA validation and enforcement as part of an ongoing measurement study at the University of Twente and the University of Liège. The survey focuses on the operational use of ASPA information: whether networks consume ASPA data to validate BGP AS paths and whether those validation results are enforced through routing policy, for example by rejecting or de-preferencing ASPA-invalid routes. It is not concerned with the publication of ASPA objects themselves. The survey takes approximately 3–5 minutes, and responses will be reported only in aggregate or anonymized form. We would greatly appreciate your input, including from networks where ASPA deployment is partial, experimental, or still under evaluation. Best regards, Savvas Kastanakis

Revocation of non-functional Delegated CAs started
by Tim Bruijnzeels 24 Sep '26

24 Sep '26

Dear working group, The RIPE NCC has finished implementation of the RIPE policy "Revocation of Persistently Non-functional Delegated RPKI CAs”: https://www.ripe.net/publications/docs/ripe-847/ https://www.ripe.net/community/policies/proposals/2025-02/ As required by the policy, a Delegated Certification Authority (CA) will be revoked by the RIPE NCC if it remains non-functional for more than 90 days. We began tracking non-functional delegated CAs on 9 June, while we worked on improvements to the RPKI dashboard and implementing our notification process. Last week, on Monday 14 September, we warned users associated with the first batch of non-functional CAs that they would soon be revoked as a result of this implementation. By this point, they had already passed the 90-day threshold. We allowed them another week to fix outstanding issues before finally revoking the 35 CAs that were still non-functional yesterday. Going forward, we will actively monitor Delegated CAs. If one is found to be non-functional, then all registered users of that CA will receive a notification after 7 days, 30 days, and 60 days. In our emails, we request that the CA is either fixed, or else revoked by the operator if they no longer need it. Otherwise, the CA will be revoked after the end of the 90 day period. The RPKI Dashboard has also now been updated to show more diagnostic information to help operators that wish to restore their CA. Kind regards, Tim Bruijnzeels Principal Engineer RPKI RIPE NCC

BGP Communities Operator Survey
by Krenc Thomas Jakob 14 Sep '26

14 Sep '26

Hi Routing WG, We are circulating a short survey on the operational use of BGP communities across several network-operator communities and would appreciate input from operators in the RIPE community. The survey has five main questions: https://forms.gle/uEc9PhBH3CrLqRu19 The questions focus on aspects of BGP community usage that are difficult to infer from public BGP measurements or documentation. The survey should take about 2–3 minutes. You do not need to be a BGP communities expert, and we are also interested in networks that make little or no use of communities. The responses will be used in aggregate to complement discussions at the Communities in the Wild workshop, co-located with ACM IMC 2026: https://bgpcommunities.org/ No sign-in or email address is required. Thanks very much for your help, Thomas Krenc IIJ Research Lab

Hi all, The Routing Working Group runs on a term limit system before re-election is needed, and one of these terms is coming up for the upcoming RIPE 93 in Sofia. This means that the seat for our co-chair Ignas (who can also run for the seat again as per the terms) is up for selection. If you're interested in helping organize the Routing WG sessions at RIPE meetings as co-chair, please reach out to routing-wg-chairs(a)ripe.net for more information Kind regards, Ben

Traffic between Cambridge (UK) and TDC-hosted destination (AS3292, Denmark) tromboning via North America — possible GTT interconnect issue
by Peter Keller 07 Sep '26

07 Sep '26

Hello, [This message was written with AI assistance because I am not an expert in this area, however a substantial amount of manual analysis lies behind it.] We're seeing persistent high latency and apparent trombone routing on traffic between an end-user site in Cambridge, UK and a destination hosted on TDC's network (AS3292) in Denmark. We'd appreciate any insight from operators familiar with this topology, particularly regarding GTT (AS3257) peering with TDC. *Context / timeline:* The end-user's building-managed ISP changed their upstream international connectivity provider. Prior to this change, routing to the affected destination appeared to transit Colt directly into TDC in Europe with no issues. Since the change, we have observed the latency problem described below. We have not been able to confirm with certainty which provider the ISP switched to, but the timing strongly correlates with the onset of the issue. *Evidence gathered:* Traceroute from Cogent's own network (London → Denmark) shows traffic routed Liverpool → Montreal (Cogent backbone) → GTT in New York → back across the Atlantic to TDC: |1 * 2 be2422.ccr82.lon05.atlas.cogentco.com (154.54.57.61) 2.062 ms 3 port-channel3464.ccr91.lhr01.atlas.cogentco.com (154.54.75.150) 1.017 ms 4 be2133.ccr22.lpl01.atlas.cogentco.com (154.54.63.237) 6.998 ms 5 be3043.ccr22.ymq01.atlas.cogentco.com (154.54.44.166) 76.101 ms 6 be2089.rcr21.ymq02.atlas.cogentco.com (154.54.45.114) 76.498 ms 7 gtt.ymq02.atlas.cogentco.com (154.54.10.178) 76.219 ms 8 ae4.cr14-nyc3.ip4.gtt.net (141.136.105.9) 74.967 ms 9 ip4.gtt.net (208.116.142.170) 75.552 ms 10 lo0-0.lynqe10.dk.ip.tdc.net (93.178.170.33) 175.604 ms| Traceroute from NTT's looking glass (London router) shows a similar pattern, this time via Ashburn/Washington DC before handing to GTT: |1 ae-13.r27.asbnva02.us.bb.gin.ntt.net (129.250.2.111) 78.084 ms 2 ae-17.a05.asbnva02.us.bb.gin.ntt.net (129.250.5.7) 77.432 ms 3 ae-0.gtt.asbnva02.us.bb.gin.ntt.net (129.250.8.22) 78.836 ms 4 ae3.cr3-was1.ip4.gtt.net (213.200.112.218) 76.768 ms 5 ip4.gtt.net (208.97.204.10) 77.534 ms 6 lo0-0.lynqe10.dk.ip.tdc.net (93.178.170.33) 181.747 ms| By contrast, a traceroute via Colt (London) reaches the same destination in three hops entirely within Europe, at ~22ms: |1 212.36.131.20 [MPLS: Label 102112 Exp 0] 2 msec 2 ae23-0.ldn4nqp1.uk.ip.tdc.net (195.66.224.64) 2 msec 3 lo0-0.lynqe10.dk.ip.tdc.net (93.178.170.33) 22 msec| *Observation:* Two independent networks (Cogent and NTT) both hand off to GTT (AS3257) to reach this TDC (AS3292) prefix, and in both cases GTT appears to carry the traffic via North America before returning it to Denmark — adding roughly 150ms round-trip versus the direct European path Colt provides. This suggests GTT's interconnection with TDC for this prefix may currently be limited to (or preferred via) North American exchange points, despite TDC clearly supporting direct European peering (as demonstrated by Colt). Would anyone with visibility into GTT's or TDC's peering topology be able to confirm whether a European interconnect exists or is planned for this route? Any pointers to the right contact for a peering/routing query at either network would also be appreciated. Thanks in advance, Peter Keller.
