Per-U colocation?
by Alex Buie 02 Jan '25

02 Jan '25

My company has cabinets at datacenters around the US, but they are relatively stubby datacenters in terms of interconnectedness. I have been thinking about what adding some backbone PoPs in more interconnected buildings would look like. However space in these (one Wiltshire, 56 Marietta) tends to be at a steep premium. Thus we would probably just want to rack a pair like 7280r3 or something and mostly just have fiber runs to our cheap stubby warehouse datacenter space. Curious about strategy here - any continental mid-sized ISPs do similar with a small footprint in the main building but the majority of their footprint offsite? Also, are there places to broker a fractional few Us of colo space in these buildings? I don’t need a full cab at thousands of dollars, that’s for sure. If you have 4U redundant power colocation at highly peered buildings (escort is ok) you can also hit me up commercially off list. Thanks yall! Happy new year. Alex

Distributed Router Fabrics
by Mike Hammett 01 Jan '25

01 Jan '25

I've noticed that the whitebox hardware vendors are pushing distributed router fabrics, where you can keep buying pizza boxes and hooking them into a larger and larger fabric. Obviously, at some point, buying a big chassis makes more sense. Does it make sense building up to that point? What are your thoughts on that direction? ----- Mike Hammett [ http://www.ics-il.com/ | Intelligent Computing Solutions ] [ https://www.facebook.com/ICSIL ] [ https://plus.google.com/+IntelligentComputingSolutionsDeKalb ] [ https://www.linkedin.com/company/intelligent-computing-solutions ] [ https://twitter.com/ICSIL ] [ http://www.midwest-ix.com/ | Midwest Internet Exchange ] [ https://www.facebook.com/mdwestix ] [ https://www.linkedin.com/company/midwest-internet-exchange ] [ https://twitter.com/mdwestix ] [ http://www.thebrotherswisp.com/ | The Brothers WISP ] [ https://www.facebook.com/thebrotherswisp ] [ https://www.youtube.com/channel/UCXSdfxQv7SpoRQYNyLwntZg ]

Fwd: [arin-announce] ARIN Will Retire the Use of FTP on 31 March 2025
by John Curran 30 Dec '24

30 Dec '24

NANOGers – Please see the following operationally relevant information about the retirement of support for FTP at ARIN on 31 March 2025 (forwarded here for your planning purposes.) After that date, one will need to use HTTP/HTTPS to access the same data archives. FYI, /John John Curran President and CEO American Registry for Internet Numbers Begin forwarded message: From: ARIN <info(a)arin.net> Subject: [arin-announce] ARIN Will Retire the Use of FTP on 31 March 2025 Date: December 30, 2024 at 2:36:44 PM EST To: "arin-announce(a)arin.net" <arin-announce(a)arin.net> From 20 September to 4 October 2024, ARIN held a consultation seeking feedback from the community on retiring FTP support, which serves data from ftp.arin.net. ARIN has operated an FTP service for various reports and templates since its inception. After reviewing the feedback received during the consultation, ARIN plans to move forward with work required to support the retirement of FTP use at ARIN, and the projected retirement date is 31 March 2025. This includes coordinating with the other Regional Internet Registries to ensure that the mirrors of the extended statistics data are migrated to HTTP/HTTPS, as well as determining an appropriate solution and implementing a method that will allow community members to run synchronization and mirroring of these data sets. All data currently available via FTP will continue to be available over HTTP and HTTPS. ARIN will provide reminders at regular intervals as we approach the retirement date. Regards, American Registry for Internet Numbers (ARIN) ------- References ARIN Consultation 2024.5 — Consultation for the Retirement of FTP Protocol Use at ARIN: https://www.arin.net/participate/community/acsp/consultations/2024/2024-5/ _______________________________________________ ARIN-Announce

Shaping the Future of ICP-2: Community Input Extended to December 2024
by John Curran 30 Dec '24

30 Dec '24

NANOGers - In October 2023, the Number Resource Organization initiated a process to undertake a significant update to Internet Coordination Policy 2 (ICP-2); the policy which specifies the criteria for establishing new Regional Internet Registries (RIRs). The Address Supporting Organization Address Council (ASO AC) has been tasked with managing the revision process, emphasizing community engagement and transparency. The ASO AC has drafted a document which outlines the principles for the proposed ICP-2 Version 2 policy, and this document is available online for review here - https://www.nro.net/policy/internet-coordination-policy-2/proposed-icp-2-ve… The ASO AC is actively seeking feedback from the Internet number resource community and the broader internet community on these proposed principles. At this stage, comments are being solicited on the principles themselves, rather than specific amendments to the text of the document. This collaborative approach aims to refine the principles before drafting a revised version of ICP-2 for further stakeholder input. To facilitate community engagement, there is a questionnaire seeking feedback that available in multiple languages, including English, French, Spanish, and Portuguese. The questionnaire is designed to gather diverse perspectives and can be completed in approximately 7–10 minutes. Recognizing the importance of comprehensive community input, the deadline for input has via the questionnaire has been extended to 6 December 2024. If you have an interest in the governance principles that should be applicable to RIRs, and a moment available to provide input, please consider doing so. More details about the principles and questionnaire are available on the NRO website - https://www.nro.net/nro-announces-that-the-deadline-for-the-icp-2-questionn… Thanks! /John John Curran President and CEO American Registry for Internet Numbers

Netflix root cause for the Tyson/Paul

Anyone from Netflix, curious if you’ll be putting out a root cause / debrief about the Tyson / Paul fight issues? I’m terribly curious about it and I think it would be very informative and helpful to everyone, to understand the point at which things broke down. -Pete- The contents of this e-mail message and any attachments are intended solely for the addressee(s) and may contain confidential and/or legally privileged information.

MPLS and Carrier Ethernet, Oh My!
by Mike Hammett 28 Dec '24

28 Dec '24

A few years back, every Tom, Dick, and Harry was touting MPLS or Carrier Ethernet NNIs with 10G ports everywhere. They still are. However, I rarely have seen that graduate to 100G ports and I don't think I've seen anyone talk about 400G ports. Is the hardware not there, or is it more a case of the technology hasn't been deployed widely, so it'll only be seen at a limited number of locations? I'm assuming it's more of the latter as the bigger hardware I've been looking at touts those features and port sizes, but maybe there's some other unadvertised limitation. ----- Mike Hammett Intelligent Computing Solutions Midwest Internet Exchange The Brothers WISP

BGP AFI or SAFI for advertising BFD status
by Douglas Fischer 23 Dec '24

23 Dec '24

I'm looking for a way to propagate the status of BFD sessions running on one router to another via BGP. Considering the versatility of BGP, I'm sure this is possible. But when researching BFD and BGP, my biggest difficulty was avoiding documents that talk about how to use BFD as a trigger for detecting the status of a BGP peer. I imagine that EVPN may have some space for this status propagation, but I couldn't find any information about it. Does any colleague have any clue about BFD session status propagation over BGP?
