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

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.

RTBH and RPKI
by Salvador Bertenbreiter 03 Sep '26

03 Sep '26

Hi all, A quick question for those using RTBH together with RPKI. How do you handle /32 announcements in IPv4 or /128 in IPv6 when the prefix has a ROA with a maxLength of /24 or /48? One option would be to extend the ROA to /32 or /128, but I’m not fully comfortable with that since it would also make other more-specifics valid. The other option would be to keep the ROA as it is and still announce the host route for RTBH, but in that case it would be RPKI Invalid. Do upstreams normally make an exception for routes marked as blackhole, or are they dropped by RPKI before the RTBH policy is applied? Creating a specific ROA at the time of the attack also doesn’t seem very practical because of propagation times. How are you handling this in production? Regards, Salvador
