[NANOG] Survey on Segment Routing deployment
by Dekinder Florian 14 Mar '25

14 Mar '25

Hello NANOG community, I recently shared a survey (2 months ago) as part of a research project on segment routing (SR) deployment practices among network operators. The goal is to gain insights into how SR is currently deployed and managed across different ASes. If you are involved in SR management in your network and if you missed the first request, I would greatly appreciate your input. The survey takes no more than 5 minutes to complete. https://docs.google.com/forms/d/e/1FAIpQLSd9d77tMC_azhcfWWCMR_nHCBlfzu8VI-v… Thank you in advance for your time and contribution! Best regards, Florian Dekinder

[NANOG] Apple-centric reboot event in Southern California
by Mel Beckman 13 Mar '25

13 Mar '25

I am in Ventura county, California, and just now at 11:30AM PT we had an iPhone, an iPad, and an iMac all crash simultaneously. The Ethernet-connected iMac had a black screen of death, and the iOS devices were on WiFi and had to be power cycled. These would seem to have to have been network-initiated events, and the iPad when it came back online said “Your device has been updated to 18.3.2”. The iPhone 16Pro, was updated to 18.3.2. yesterday and displayed no unusual message upon power-on. The iMac is an older model Retina 5K 27” from 2014 running MacOS 10.11.6. I’m reporting this here in case an Apple-initiated automatic network update process is running amok. In my experience, Apple products never update without telling you first, and even automatic updates have always happened in the dead of night and require the device to be plugged into power. The probability of three devices, all from the same manufacturer, randomly crashing simultaneously, seems remote. Which is why I suspect something network driven. None of our linux, android, or windows devices were affected. Has anybody else seen something similar? -mel

[NANOG]Proposal for HENETIX: A Global IXP with High-Discounted Peering and Transit Services
by Volkan SALiH 10 Mar '25

10 Mar '25

*Subject:* Proposal for HENETIX: A Global IXP with High-Discounted Peering and Transit Services *Dear Mr. Mike Leber, and interested NANOG members * I hope this email finds you well. I am writing to you regarding the recent pricing structure adjustment for BGP tunnelbroker services, which were previously offered as a free (feeless) solution. Given the increasing demand for cost-effective and scalable interconnectivity solutions, I would like to propose the establishment of *HENETIX*, a global Internet Exchange Point (IXP) designed to facilitate high-discounted peering and transit services across a worldwide network. The Concept of HENETIX HENETIX would operate as a global IXP, providing Layer 2 transport services without additional per-port or per-transport costs, allowing participants to exchange traffic with remote peers efficiently. Unlike traditional IXPs that impose substantial fees for remote peering or rely on third-party transport providers, HENETIX would integrate transport services within a unified pricing model. This approach would align with industry trends favoring cost efficiency, network expansion, and improved global routing performance. Supporting Global Connectivity: Comparable Industry Examples Several networks and IXPs around the world have adopted similar models to reduce costs and improve accessibility. Some notable examples include: * *PacketFabric* and *Megaport*: Both platforms offer global Layer 2 connectivity with a simplified pricing model that integrates transport within the overall service, enabling customers to reach multiple regions without complex fee structures. * *Equinix Fabric*: Provides global interconnection across multiple markets with predictable pricing, reducing the barriers for enterprises and ISPs to participate in global exchanges. * *DE-CIX, AMS-IX, and LINX*: While these IXPs operate within traditional frameworks, they have introduced remote peering models that enable global reach with relatively lower costs compared to traditional carrier-based transport. Legal and Regulatory Considerations The need for affordable interconnection services is not only a market demand but also a recognized regulatory priority in many regions. Organizations such as the *FCC (Federal Communications Commission, USA)* and the *European Commission* have emphasized the importance of neutral and cost-effective peering points to foster competition and improve internet resilience. Additionally, policies encouraging open interconnection are being promoted by various regulatory bodies to prevent monopolistic pricing practices in the transit market. Benefits of HENETIX A HENETIX platform would provide significant advantages to both large-scale and emerging network operators: 1. *Cost Reduction*: A unified membership model would eliminate high transport fees, making global interconnection more affordable. 2. *Enhanced Network Performance*: By reducing dependency on Tier-1 transit providers, participating networks would achieve better latency, redundancy, and overall performance. 3. *Simplified Peering*: A single interconnection framework would allow participants to seamlessly peer with networks worldwide without dealing with individual transport providers. 4. *Increased Market Accessibility*: Smaller ISPs, data centers, and cloud providers would be able to join a global interconnection fabric without financial constraints. 5. *Scalability*: As internet traffic demands continue to grow, a streamlined interconnection model would ensure scalability without prohibitive infrastructure investments. Proposal and Next Steps Given HE.NET's extensive network infrastructure and existing peering relationships, establishing HENETIX as a global IXP would be a strategic extension of your current services. By leveraging your existing assets and expertise, this initiative could position HE.NET as a leader in cost-effective global interconnection solutions. I would appreciate the opportunity to discuss this proposal further and explore potential strategies for implementation. Please let me know a convenient time for a meeting or call to delve deeper into this concept. Thank you for your time and consideration. I look forward to your thoughts on this matter. Best regards, VOLKAN SALİH ANTAKYA/HATAY/TURKIYE +90 540 415 5555 +90 540 489 9999

by Matt McMullen 07 Mar '25

07 Mar '25

I am having difficulty opening a request with Netflix OpenConnect. They have an old ticket in their system for our ASN and I can't access the portal to close it so I can open a new request. Can a person from Netflix OpenConnect please reach out to me? Matthew McMullen Network Manager main: 816.710.9030 ext. 9030 Conexon<https://conexon.us/> [Logo Description automatically generated]
