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

Hi All, adding a few more group emails to see if we can get help - ripe-list(a)ripe.net, and others. Please read the thread. We are having a major bandwidth issue coming from multiple places around the world to multiple ISPs in Portugal. This is not isolated to us. Feel free to reach out directly if you have questions. Any help here would be appreciated. ________________________________ From: Justin Cottrell <justin.cottrell(a)mirazon.com> Sent: Wednesday, September 30, 2026 10:39 AM To: Pajevic, Aleksandar (External) <apajevic.ext(a)libertyglobal.com>; Pandya, Akshay <AkshayPandya(a)WireCo.com>; Steven Van Steen <svansteen(a)libertyglobal.com>; Liberty Global - CSD IP Infrastructure and Voice <CSDIPInfrastructureandVoice(a)libertyglobal.com>; noc(a)vodafoneziggo.com <noc(a)vodafoneziggo.com>; b2b.ops(a)vodafoneziggo.com <b2b.ops(a)vodafoneziggo.com>; Liberty Global Central Network Support <cns(a)libertyglobal.com>; LibertyGlobal-DL- CoreNetworkOperations <CoreNetworkOperations(a)libertyglobal.com> Cc: Liberty Global Peering Team <peering(a)aorta.net>; Liberty Global-Mail2Ticket Update <mail2ticketupdate(a)libertyglobal.com>; Baumgarten, Rick <RickBaumgarten(a)WireCo.com>; Ribeiro, Artur <ArturRibeiro(a)WireCo.com>; PaulBratcher <PaulBratcher(a)wireco.com> Subject: Re: [External] P4|INC000005996181|Bandwidth/Path issues from multiple providers to Portugal HI All, we are really suffering from this issue. Since it happens from multiple exiting ISPs it's a weird one. To answer your question @Pajevic, Aleksandar (External)<mailto:apajevic.ext@libertyglobal.com> - we have full communication, but when we push the TCP session with a good bit of bandwidth, that's when we see the issue. So, it is a TCP issue transiting the path. Please check some of the docs I sent; we clearly show that. Can we all get on a meeting to discuss? I can show examples, etc and we all might be able to get to the bottom of it. This is not just us - it seems to be a global transit issue. Could you guys test as well from Netherlands/Portugal/US, etc? ________________________________ From: Pajevic, Aleksandar (External) <apajevic.ext(a)libertyglobal.com> Sent: Monday, September 28, 2026 3:48 AM To: Pandya, Akshay <AkshayPandya(a)WireCo.com>; Justin Cottrell <justin.cottrell(a)mirazon.com>; Steven Van Steen <svansteen(a)libertyglobal.com>; Liberty Global - CSD IP Infrastructure and Voice <CSDIPInfrastructureandVoice(a)libertyglobal.com>; noc(a)vodafoneziggo.com <noc(a)vodafoneziggo.com>; b2b.ops(a)vodafoneziggo.com <b2b.ops(a)vodafoneziggo.com>; Liberty Global Central Network Support <cns(a)libertyglobal.com>; LibertyGlobal-DL- CoreNetworkOperations <CoreNetworkOperations(a)libertyglobal.com> Cc: Liberty Global Peering Team <peering(a)aorta.net>; Liberty Global-Mail2Ticket Update <mail2ticketupdate(a)libertyglobal.com>; Baumgarten, Rick <RickBaumgarten(a)WireCo.com>; Ribeiro, Artur <ArturRibeiro(a)WireCo.com>; PaulBratcher <PaulBratcher(a)wireco.com> Subject: RE: [External] P4|INC000005996181|Bandwidth/Path issues from multiple providers to Portugal ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ NkdkJdXPPEBannerStart External Sender - From: ("Pajevic, Aleksandar (External)" <apajevic.ext(a)libertyglobal.com>)<https://us1.proofpointessentials.com/email-details/?k=k1&payload=53616c7465…> This message came from outside your organization.

Packets do not pass Liberty Global network at all. I have found some that do pass Liberty Global network, and I would like to focus on one flow, from one source IP to one destination IP and the other way around. We peer with VodafoneZiggo and there is no congestion and no packet loss on that interface, and also no congestion and no packet loss on the interface to Vodafone AS1273 in Amsterdam. Marked below. Those MTR are not sufficient, only 1 packet sent, should be 1000 min and preferably larger packets. But on those 2 MTRs we can see there is no latency increase, < 50 ms is normal latency between the Netherlands and Portugal. 1 packet sent and receive on 148.69.181.212. Also please allow ICMP traffic on of server with IP 93.117.236.142, otherwise we do not know what is percentage of the packet loss on that IP.

The most severe symptom is reduced TCP throughput when traffic is transmitted FROM Portugal toward international destinations. Testing has been performed from two separate Portugal locations, PTMA and Oliveira, using multiple remote destinations and multiple test methodologies. The most important control test is communication between the two Portugal locations. PTMA and Oliveira can sustain approximately 480–500 Mbps using a SINGLE TCP connection when communicating with each other. When essentially the same testing is performed from Portugal toward international destinations, individual TCP flows can fall to approximately 30–80 Mbps. Multiple parallel TCP streams frequently recover several hundred Mbps of aggregate throughput. This strongly suggests that the affected circuits have substantially more aggregate capacity than an individual affected TCP flow is able to utilize. AS33915 appears in routing associated with our Netherlands location and is therefore one of the networks we are asking to assist with investigation. We are not asserting that AS33915 is responsible for the condition. We are requesting assistance determining whether the impairment occurs within AS33915, at an interconnection/peering boundary, or elsewhere along the international path. ________________________________ 1. Primary Sites PTMA – Portugal Public test endpoint: 193.126.229.227 PTMA has been tested using two independent Internet connections. Testing has also been performed with the customer firewall and switching infrastructure removed from the path by connecting the test endpoint directly to the ISP circuit. Oliveira – Portugal Public test endpoint: 83.240.185.210 Oliveira is a physically separate Portugal location and provides an important independent comparison with PTMA. Netherlands Public test endpoint: 93.117.236.142 Routing associated with this destination traverses/reaches AS33915. Poland Public test endpoint: 95.171.126.204 Additional private/VPN testing has also been performed against the Poland network. ________________________________ 2. Critical Control Test – Portugal to Portugal The most useful baseline is PTMA ↔ Oliveira. These sites are independent Portugal locations. Single TCP PTMA → Oliveira: ~501 Mbps Oliveira → PTMA: ~484 Mbps Parallel TCP PTMA → Oliveira, 8 streams: ~505 Mbps Oliveira → PTMA, 8 streams: ~482 Mbps Significance There is essentially no severe single-flow TCP penalty between the Portugal sites. A single TCP connection is capable of utilizing approximately 500 Mbps. This is important because it demonstrates that neither Portugal endpoint has an inherent 30–80 Mbps TCP limitation. It also provides a known-good baseline against which the international tests can be compared. ________________________________ 3. PTMA ↔ Netherlands This has produced some of the clearest directional results. Single TCP Netherlands → PTMA: ~346 Mbps PTMA → Netherlands: ~42.2 Mbps This represents approximately an 8:1 difference between directions during the comparable test. Eight Parallel TCP Streams Netherlands → PTMA: ~909 Mbps PTMA → Netherlands: ~292 Mbps The ability to reach approximately 292 Mbps outbound using parallel connections while a single connection reaches only approximately 42 Mbps demonstrates that substantially more aggregate path capacity exists than the single TCP connection can utilize. UDP Additional public-path UDP testing delivered approximately: 300 Mbps offered → ~300 Mbps delivered 400 Mbps offered → ~401 Mbps delivered A 500 Mbps offered-load test averaged approximately 384 Mbps and exhibited significant short-term throughput variation. Again, the path can transport substantially more traffic than the affected ~42 Mbps single TCP flow. Latency PTMA ↔ Netherlands RTT is approximately: 46 ms TCP PsPing testing was stable and did not show persistent end-to-end loss during the referenced test. ________________________________ 4. Oliveira → Netherlands A second Portugal site reproduces the same general behavior. Single TCP Oliveira → Netherlands: ~31 Mbps Eight Parallel TCP Streams Oliveira → Netherlands: ~466 Mbps This is a particularly significant result. The same Oliveira endpoint that sustains approximately 484 Mbps using ONE TCP connection to PTMA sustains only approximately 31 Mbps on a single TCP connection toward the Netherlands. Adding parallel connections increases aggregate throughput to approximately 466 Mbps. Therefore: Oliveira → PTMA: ~484 Mbps single TCP Oliveira → Netherlands: ~31 Mbps single TCP Oliveira → Netherlands: ~466 Mbps with 8 TCP streams This is difficult to reconcile with a simple bandwidth limitation at the Oliveira site. ________________________________ 5. Oliveira → Poland The issue is not limited to the Netherlands test. Testing from Oliveira toward Poland also demonstrated reduced outbound TCP performance. Single TCP Oliveira → Poland: ~78 Mbps Eight Parallel TCP Streams Oliveira → Poland: ~143 Mbps Although the characteristics are not identical to the Netherlands path, international outbound performance is again significantly below the approximately 480–500 Mbps single-flow performance demonstrated between the two Portugal sites. ________________________________ 6. PTMA → Poland Private/VPN testing has also demonstrated outbound degradation from PTMA toward Poland. One eight-stream PTMA → Poland test achieved approximately: ~90 Mbps aggregate UDP testing at lower offered rates performed substantially better from a packet-loss perspective. These tests involve VPN/private infrastructure and are therefore treated as supporting evidence rather than our primary public-Internet control. Our strongest evidence remains the direct public endpoint testing. ________________________________ 7. Additional Geographic Testing Testing has also been performed from Germany and the United States. Germany testing demonstrated that our Netherlands endpoint is capable of receiving substantially higher aggregate TCP throughput from another geographic region. For example, Germany → Netherlands using eight TCP streams with a 1 MB window reached approximately: ~564 Mbps The same Netherlands endpoint therefore is not simply capped at the low throughput observed from Portugal. United States/private-path testing has also been performed, although because those tests include VPN infrastructure we do not use them as the primary evidence for this escalation. The public Portugal ↔ Netherlands and Portugal ↔ Portugal comparisons provide a much cleaner control. ________________________________ 8. PTMA Direct-to-ISP Testing A significant amount of effort has been made to eliminate customer equipment as a cause. At PTMA, testing has been performed with the test computer connected directly to the ISP service. This removes the following equipment/functions from the tested path: * FortiGate firewall * IPsec VPN * UTM/security inspection * Cisco access switching * Customer LAN infrastructure The international behavior remained reproducible. Testing was subsequently performed through a SECOND independent PTMA Internet provider. The two PTMA providers use materially different upstream transit paths. Despite this, similar destination-dependent and flow-dependent performance behavior was observed. This significantly reduces the likelihood that a single PTMA firewall, switch, ISP access circuit, or unique upstream carrier is responsible for the entire issue. ________________________________ 9. Flow-Count Dependency One of the most repeatable characteristics is the difference between single and parallel TCP flows. Examples: PTMA → Netherlands: Single TCP: ~42 Mbps 8 TCP streams: ~292 Mbps Oliveira → Netherlands: Single TCP: ~31 Mbps 8 TCP streams: ~466 Mbps PTMA → Oliveira: Single TCP: ~501 Mbps 8 TCP streams: ~505 Mbps The Portugal domestic path behaves normally. The international paths exhibit dramatically greater dependence on parallel TCP flows. This suggests investigation should focus on conditions capable of disproportionately affecting individual long-lived TCP flows rather than solely aggregate interface utilization. Potential areas for investigation include, but are not limited to: * Low-level packet loss * TCP retransmissions * Queue congestion * Microbursts * Policers * Traffic shaping * ECMP/flow hashing * Congested individual LAG/ECMP members * Peering/interconnection congestion * Asymmetric routing * Receive-window/congestion-window interaction * Packet reordering * Path-specific MTU/MSS behavior These are investigation areas, not conclusions regarding the root cause. ________________________________ 10. Routing / AS33915 Observation During testing toward the Netherlands endpoint, routing associated with the destination enters or converges toward the AS33915 network. Observed AS33915-associated addresses on tested paths have included: 213.51.64.x 213.51.7.187 Earlier testing from PTMA's primary ISP reached the Netherlands through an AS6453 path before entering the Netherlands-side network. Testing through PTMA's second provider followed a materially different Vodafone/Cable & Wireless transit path. Despite the different upstream paths from Portugal, similar performance behavior was observed toward the Netherlands destination. This makes the common downstream portion of the path particularly interesting. However, we want to emphasize: We are NOT concluding that AS33915 is responsible. The problem could exist: * within an upstream transit network, * at the interconnection with AS33915, * within AS33915, * on the destination access network, * or as the result of an interaction between multiple networks. We are requesting AS33915's assistance specifically because visibility from within the network is required to distinguish these possibilities. ________________________________ 11. What We Would Like AS33915 to Investigate We would appreciate review of the path toward: 93.117.236.142 during synchronized testing from our Portugal endpoints. Specifically, we would appreciate examination of: 1. Interface utilization and congestion along the relevant path. 1. Interface discards or queue drops. 1. LAG/ECMP member utilization and errors. 1. Whether individual TCP flows could be consistently hashing onto a congested or impaired member. 1. Policers or traffic-management policies affecting traffic from the relevant Portugal prefixes. 1. Peering/interconnection utilization toward the Portugal transit providers. 1. BGP path selection for traffic toward and from: * 193.126.229.227 * 83.240.185.210 1. Return-path routing from AS33915 toward both Portugal destinations. 1. Any asymmetric routing between the forward and reverse paths. 1. Packet loss that may be too small to appear clearly in ordinary ICMP testing but significant enough to affect long-RTT TCP throughput. 1. Any known congestion or capacity issue at the relevant European interconnection points. ________________________________ 12. Proposed Coordinated Test We would be happy to coordinate a live test with the AS33915 network team. The preferred test would use: Portugal: 193.126.229.227 Netherlands: 93.117.236.142 We can run the following sequence while AS33915 monitors the relevant interfaces: 1. Single TCP stream – Portugal → Netherlands 1. Single TCP stream – Netherlands → Portugal 1. Eight TCP streams – Portugal → Netherlands 1. Eight TCP streams – Netherlands → Portugal 1. Controlled UDP at 100 Mbps 1. Controlled UDP at 200 Mbps 1. Controlled UDP at 300 Mbps 1. Traceroute/MTR in both directions We can provide exact timestamps to correlate each test with network telemetry. Packet captures can also be collected simultaneously at both endpoints if required. ________________________________ 13. Summary of Key Evidence The core issue can be summarized very simply: PTMA → Oliveira, Portugal: ~501 Mbps SINGLE TCP Oliveira → PTMA, Portugal: ~484 Mbps SINGLE TCP PTMA → Netherlands: ~42 Mbps SINGLE TCP Oliveira → Netherlands: ~31 Mbps SINGLE TCP Yet parallel connections can recover hundreds of Mbps on the affected international paths. This means the Portugal systems are demonstrably capable of approximately 500 Mbps single-flow TCP performance. The severe degradation emerges primarily when traffic traverses longer/international paths. The condition has been reproduced: * From two separate Portugal sites * Through multiple Portugal Internet providers * With customer firewall/switch infrastructure removed in direct testing * Using public Internet endpoints * In both single and parallel TCP testing * With UDP demonstrating additional aggregate path capacity We therefore believe this warrants investigation at the IP transit/peering/core-network level. Again, we are not assigning fault to AS33915. We are asking for assistance determining whether the impairment occurs inside AS33915, at an interconnection involving AS33915, or elsewhere along the path. We can provide raw iPerf3 results, PsPing output, traceroutes, PathPing output, source/destination addresses, packet captures and exact timestamps. Thank you for any assistance in getting this case to the appropriate IP Core / Backbone / Peering engineering team.

We have been troubleshooting this extensively with our ISPs and have direct iPerf, PsPing, traceroute and path data from multiple European locations. The interesting finding is that our Portugal sites can sustain approximately 480–500 Mbps on a single TCP flow when communicating within Portugal, but international single-flow TCP performance drops dramatically. For example, Oliveira, Portugal → Netherlands drops to approximately 31 Mbps on a single TCP flow, while 8 parallel flows over the same path can reach approximately 466 Mbps. We have also reproduced related behavior from two separate Portugal locations/providers, and earlier traces toward our Netherlands endpoint (93.117.236.142) converge at/near AS33915. I am not assuming AS33915 is the cause, but I am trying to find someone who could help review the relevant peering/core path or point us toward the correct NOC/network engineering team. I can provide exact timestamps, source/destination IPs, traceroutes and complete iPerf results if helpful. Please let me know what I can do to keep our troubleshooting going.

Formo parte de nuestro equipo.Me dirijo a usted porque muchas empresas con atención telefónica frecuente comprueban que no siempre resulta posible responder a tiempo todas las llamadas. Cuando esto ocurre, además de perderse consultas, reservas, incidencias o nuevas oportunidades, también puede resentirse la imagen de atención al cliente.En SVAE prestamos un servicio humano y continuo de atención telefónica 24/7 en nombre de cada empresa. Respondemos siguiendo el protocolo que se nos indique, filtramos, registramos y derivamos cada aviso con orden y criterio, para que su negocio mantenga una atención profesional sin necesidad de ampliar plantilla.Como medida práctica, suele ser útil revisar en qué franjas se acumulan más llamadas sin respuesta y qué tipos de avisos conviene priorizar. Con una operativa clara, se evitan pérdidas de tiempo y gestiones mal atendidas.Trabajamos con un enfoque de precio honesto, ajustado a la necesidad real de cada empresa. Si en algún momento le resulta de utilidad, puede conservar mis datos como contacto de confianza para este tema.Un cordial saludo.

Hallo Schatz
by Davis Tkachenko 01 Oct '26

01 Oct '26

Lieber Geliebter, Ich bin Fräulein Davis Tkachenko, die einzige Tochter des verstorbenen Dr. Tkachenko. Mein Vater war ein sehr wohlhabender Kakaohändler mit Sitz in Abidjan, dem Wirtschaftszentrum der Elfenbeinküste, bevor er auf einer Geschäftsreise von seinen Geschäftspartnern vergiftet wurde. Als meine Mutter starb, als ich noch ein kleines Baby war, kümmerte sich mein Vater besonders liebevoll um mich, da ich mutterlos und Einzelkind war. Bevor mein Vater in einem privaten Krankenhaus hier in Abidjan starb, rief er mich heimlich an sein Krankenbett und sagte mir, dass er 5.500.000,00 Euro besaß. Fünf Millionen fünfhunderttausend Euro befinden sich noch immer auf einem Treuhandkonto bei einer Bank hier in Abidjan. Er sagte, er habe meinen Namen als seine einzige Tochter angegeben, damit meine nächsten Angehörigen dieses Geld einzahlen könnten. Er erklärte mir auch, dass er aufgrund dieses Vermögens von seinen Geschäftspartnern vergiftet worden sei und dass ich mir einen ausländischen Partner in einem Land meiner Wahl suchen solle, wohin ich das Geld überweisen und es investieren könne, um mein Leben zu retten. Er fürchtet auch um mein Leben. Ich bitte Sie höflichst um Ihre Unterstützung in folgender Weise: 1) Bereitstellung eines Bankkontos für die Überweisung des Geldes. 2) Übernahme der Treuhänderschaft für dieses Geld. 3) Organisation meiner Einreise in Ihr Land für ein weiterführendes Studium und Beantragung einer Aufenthaltserlaubnis. 4) Anlage des Geldes mit mir. Sobald der Betrag erfolgreich auf Ihrem Konto eingegangen ist, bin ich bereit, Ihnen 30 % des Gesamtbetrags als Aufwandsentschädigung anzubieten. Bitte teilen Sie mir Ihre Unterstützungsmöglichkeiten mit, da ich mit dem Abschluss dieser Transaktion innerhalb von sieben (7) Tagen rechne. Ich warte nun auf Ihre Antwort. Vielen Dank. Fräulein Davis Tkachenko.
