Anyway, y'all have attackers using various VPS instances on your network to conduct coordinated brute-force ssh attacks, and you should make that stop yesterday. Details? Logs? Yes, yes, I know, I did try to send them to you -- but see the above for the explanation covering why you didn't receive them. Also: for the love of dog, fix this nonsense. ---rsk

Google is not turning up any new peering on IXs?
by Will OBrien 04 Sep '25

04 Sep '25

We recently turned up a new IXP and I’m going through the motions of arranging the usual peers, etc. I’m extremely surprised by this one: Public Peering Google no longer accepts new peering requests at internet exchanges (IXPs). However, Google maintains dedicated connectivity to the internet exchanges (IXPs) listed in our PeeringDB entry<https://www.peeringdb.com/asn/15169>. We also maintain existing BGP sessions across internet exchanges where we are connected. For networks who do not meet our PNI requirements Google will serve those networks via indirect paths. I can only presume that someone who doesn’t pay for cross connect fees came up with this plan. This feels short sighted at the least. Considering the benefits of peering, I have to express some dismay at this disservice to the internet in general. Anyone from Google care to explain what appears to be a willful withdrawal of support for the IXP community?

Genius or Ridiculous?
by Mike Hammett 31 Aug '25

31 Aug '25

My current project is a voice-related project, but how ridiculous would it be to get a line of service from my competitors at my main office for me to do diagnostics from? Internet from Comcast, Frontier, etc. Voice from Frontier, Comcast, AT&T wireless, VZW, and T-Mobile? I'm currently in a situation where I have to engage customers (or the family of employees) to place test calls for me to collect data on because I can't do it any other way. ----- Mike Hammett Intelligent Computing Solutions Midwest Internet Exchange The Brothers WISP

APRICOT 2026: Call for Volunteers (Programme Committee)
by Mark Tinka 31 Aug '25

31 Aug '25

Hello all. The APRICOT 2026 Organising Committee would like to welcome everyone to join us in Jakarta, Indonesia, from 5th - 12th February 2026. The APRICOT 2026 PC (Programme Committee) is responsible for the solicitation and selection of suitable presentations and tutorial content for the APRICOT 2026 conference (https://2026.apricot.net/) We are now seeking VOLUNTEERS from the community to join the APRICOT 2026 PC to assist with the development of the programme for APRICOT 2026. Eligible PC candidates must have attended recent APRICOT events, be active members of their local NOG (Network Operators Group) in the Asia Pacific region, have broad technical knowledge of Internet operations, and have good familiarity with the format of APRICOT. Having constructive opinions and ideas about how the programme content might be improved is of high value too. PC members are expected to work very actively to solicit content, follow-through with speaker updates and review submissions for technical merit. The PC meets by conference call, weekly in frequency during the three months prior to APRICOT. While participation in the weekly calls is not obligatory, active participation in content reviews is required at all times to help the PC reach consensus. PC members who are unable to fully participate in the programme development will be excused from the PC. If you are interested in joining the PC and meet the above eligibility criteria, please send a brief note to "pc-chairs at apricot.net". The note must include affiliation (if any) and a brief description about why you would make a good addition to the PC. The PC Chairs will accept nominations received by 17:00hrs UTC+8 on Sunday 7th September 2025, and will announce the new PC shortly thereafter. Many thanks!

Newbie Needs Help: someone is announcing less-specific IPv6 (BGP) route on top of me
by Pirawat WATANAPONGSE 30 Aug '25

30 Aug '25

Dear Gurus, Radar tool by Qrator [Reference: https://radar.qrator.net ] claims that Zenlayer Inc. [AS4229] is “umbrella-ing” me by announcing ‘2400::/12’ on top of my more-specific address block. The tool classifies it as a type of hijacking. [Disclaimer: apologies to Zenlayer if you didn’t do it; but that’s the information I received] My neighboring organization also has a more-specific block that falls under The Umbrella too. However, other tools (https://stat.ripe.net , https://irrexplorer.nlnog.net , https://bgp.he.net , etc.) seem unable to see that particular announcement. Questions: 1. Is Qrator claim true? (because I have already tried but cannot verify) 2. If so, should I be concerned? Even though I already ROA-ed *and* IRR-ed my own block, but if “the other end” doesn’t validate, it won’t do any good, correct? (Oh, yeah, the other end also has to somehow “not see” my longer-prefix. But that can happen as well, no?) 3. In that case, what more do I must do? I would extremely appreciate someone helping me out on this matter. Best Regards, Pirawat.

TDM Voice Issue
by Mike Hammett 30 Aug '25

30 Aug '25

Normally, I'd post on VoiceOps (and I did), but that list is currently quite neutered. Frontier wholesale support was of little help. Can anyone help in a CLLI code lookup to see who that ID corresponds to? I have a circuit ID, but I only know my CLLI and Frontier's CLLI code, not who the other entity is. I also see a "Carrier Identification Parameter: 5483" if that means anything to anyone. ----- Mike Hammett Intelligent Computing Solutions Midwest Internet Exchange The Brothers WISP
