Request for RIPE Atlas credits - CS student at ETH Zürich
by Nikolas Kühnlein 30 Mar '26

30 Mar '26

Hi all, My name is Nikolas Kühnlein and I am a computer science student at ETH Zürich, currently taking a course on computer networks. As part of my studies I have been exploring traceroute analysis and IP geolocation using latency triangulation — specifically trying to verify the physical location of intermediate hops using RTT measurements from distributed vantage points, rather than relying on WHOIS or commercial geolocation databases. I recently discovered RIPE IPmap and was impressed by how accurately it placed a Google border router in Zürich (contradicting a WHOIS record pointing to Mountain View, CA). I would like to run my own ping measurements from European probes to a small set of hop IPs from my traceroutes, to understand the triangulation method hands-on. As a new user I have no credits, and I am looking for a small donation to get started — a few million credits would be more than enough for what I have in mind. My RIPE Atlas account is registered under: nikshop(a)takuu.de I am happy to share my findings with the community. Thank you in advance for any help. Best regards, Nikolas Kühnlein ETH Zürich

CfP: Workshop on Negative results in Network measurements (NetNet)
by Alexandrina Ioana Livadariu 26 Mar '26

26 Mar '26

Hello all, We are organizing a workshop on Negative results in Network measurements (NetNet) this year. The workshop is part of ACM SIGCOMM’26 and will take place in Denver, Colorado, USA. The workshop invites submissions that report and reflect negative results in network measurement studies. The main goal is to foster a constructive discussion on lessons learned from studies in which methods, datasets or experimental designs did not yield the expected results. Submissions should focus on fundamental issues related to measurement approaches, methodology, and underlying assumptions, rather than on non-fundamental issues such as implementation bugs or misconfigurations. Focusing on the critical parts of the experiment, the workshop aims to strengthen rigor, promote transparency and improve methodology practices in network measurement research. We are planning to open the workshop for short papers (two and six pages) focusing on one problem where the authors dealt with negative results. Submissions must be original, unpublished work, and not under consideration at another conference or journal. Important dates: Submission deadline: May 1, 2026 (AoE) Acceptance deadline: June 5, 2026 Camera ready: June 20, 2026 Workshop date: August 17, 2026 (co-located with ACM SIGCOMM’26) Submission: https://netneg26.hotcrp.com/ Full Call for Papers: https://conferences.sigcomm.org/sigcomm/2026/netneg/ We look forward to your submissions and participation! Best regards, Ioana Livadariu & Mattijs Jonker

Request for access to RIPE Atlas HTTP measurements with full URL support
by Andrey Validenko 19 Mar '26

19 Mar '26

Hi RIPE Atlas team, I would like to request access to HTTP measurements with full URL/path support. I am currently developing a project focused on monitoring domain availability and detecting potential network interference (DNS, IP, HTTP-level) across different countries and ISPs using RIPE Atlas. At the moment, standard measurements allow testing domains at a basic level, but for my use case it is important to test specific URLs and paths (e.g. https://domain.com/path) as blocking or filtering often happens on particular endpoints rather than the root domain. Additionally, I am working on applying these measurements to anti-phishing and malware detection use cases. Many phishing campaigns rely on specific URL paths, and being able to measure HTTP responses (status codes, headers, response size) for those paths across different networks would significantly improve detection accuracy. Concretely, this capability would allow me to: - detect selective blocking or filtering of specific URLs rather than entire domains - identify abnormal HTTP responses (e.g. block pages, injected content) on targeted paths - compare behavior across ISPs and regions to detect network-level anomalies - improve heuristics for early identification of malicious or compromised infrastructure I understand that this feature may require special permissions due to resource usage, and I am committed to using it responsibly with a limited and controlled number of measurements. I would be happy to provide more details about my use case if needed. Thank you for considering my request. Best regards, Andrew Validenko Andrew_CrushPhish

Latest RIPE Atlas web update kills older browsers
by Ernst J. Oud 17 Mar '26

17 Mar '26

Hi, I just noticed that atlas.rip.net has apparently been updated. Slightly older browsers now only give a blank page, for instance Safari on iPadOS 18.1 and Opera 78 on Windows 10. Not a huge problem, currently updating my trusty iPad… always holding this off until Apple updates are reported as more stable. Regards, Ernst J. Oud

Atlas UI updates 2026-03-16
by Stephen Suess 16 Mar '26

16 Mar '26

Hello Atlas friends, We have just released an update to the Atlas frontend with the following notable changes Updated RIPE NCC Navigation: We've rolled out an updated navigation across RIPE NCC services, you can read about it here: https://labs.ripe.net/author/antonella-de-bellis/rethinking-ripe-ncc-naviga… Path Divergence Use Case: Path Divergence is the counterpart to Khipu. While Khipu visualises paths from many probes to a single target, Path Divergence visualises paths from a single probe to multiple targets across different measurements. You can read about the tool in the docs: https://atlas.ripe.net/docs/tools-and-code/path-divergence And you can try it out here: https://atlas.ripe.net/use-cases/path-divergence In addition, we have: - New region and multi-country probe selection when creating or editing measurements - Popup links out to path analysis and khipu from traceroute measurement details - In page path analysis time window controls - and a bunch of fixes and tweaks You can see the full list of what has changed in the release notes: https://atlas.ripe.net/docs/releases/website_index/2026-03-16 As always, we welcome your feedback and would love to know what you think. Kind regards, Stephen Atlas UI

Credit Sponsoring for DNS Research
by Richter, Robert 03 Mar '26

03 Mar '26

Hello everybody, Currently, we’re working on DNS data for Starlink. Sadly, I have already burned through all 20M of my RIPE Atlas credits, but I would like to continue my measurements. Further measurements would probably require around 35M credits. If somebody has some spare credits lying around, I’d be happy to put them to good use 😊 My RIPE Atlas Mail: robert.richter(a)rrcomtech.com Thanks in advance! Best regards, Robert

Probe v3 SW Corrupted
by ripe＠brite.cz 26 Feb '26

26 Feb '26

Hi team, I have issue with probe 34512, on atlas.ripe.net it keeps showing Flash Drive Filesystem Corrupted. I tried 4 different USB flash disks, all proven working elsewhere, even tried to swap this probe with another probe's power supply + network + USB drive, no matter what I do it keeps in the bad state. When no USB drive connected it correctly shows NO-USB SOS messages, when I plug any USB drive it will correctly detect and show its name and properties, such as Size=15155200 ro=0 SerialNumber=C860008862F0CF610A0D3704 Vendor=0930 ProdID=6544 Rev= 1.00 Manufacturer=Kingston Product=DataTraveler 2.0 or Size=242024448 ro=0 SerialNumber=07210B4816170B42 Vendor=13fe ProdID=6000 Rev= 1.10 Manufacturer= Product=Patriot Memory but still no go. The lights on the probe are [on] [off] [slow blinking] [fast blinking] [on (button one)]. If the internal firmware is corrupted, is there a way how to resurrect it? Cheers from Czechia Jiri

RootViz Dashboard
by Giovane C. M. Moura 26 Feb '26

26 Feb '26

Folks, [Sorry for cross posting] We’ve just published a new open dashboard called RootViz[0]. It shows real-time data from all RIPE Atlas probes, letting you see reachability and latency between probes and each Root Server over IPv4 and IPv6. It’s a useful complement to DNSMON[1]: DNSMON uses only Atlas anchors, whereas RootViz uses all probes (Atlas does the heavy lifting of measuring ever server every 4min, we just process it and visualise it). We published a short blog describing it too[2]. If you’re interested in how the root servers are performing globally, this should be a handy tool. Any ideas, feedback or suggestions are more than welcome. (We are looking into releasing it open-source, as it can be used to monitor any DNS service -- we do this for one of the .nl authoritatives) Thanks, /giovane -- SIDN Labs [0] https://rootviz.sidnlabs.nl [1] https://dnsmon.ripe.net/ [2] https://www.sidnlabs.nl/en/news-and-blogs/rootviz-new-root-dns-reachability…

FreeBSD/MacOS probe
by Jared Mauch 12 Jan '26

12 Jan '26

I’m looking for people to test out my attempted FreeBSD/MacOS changes to shift a few calls to POSIX compliant and other tweaks to make it build on other operating systems. You can try to build from this git repo: https://github.com/jaredmauch/ripe-atlas-software-probe I would request comments go here: https://github.com/RIPE-NCC/ripe-atlas-software-probe/pull/135 Or possibly in this issue which originated from someone else, but the recent note from Randy had me look at the codebase. https://github.com/RIPE-NCC/ripe-atlas-software-probe/issues/123 Hopefully this is useful and might be able to be merged back in, but I know this may cause some troubles due to the busy box parent as well. - Jared

Atlas UI updates 2026-01-05
by Stephen Suess 05 Jan '26

05 Jan '26

Happy New Year, We have just released an update to the Atlas frontend with several new features to help you customise and explore your measurement data. Dashboard customisation: You can now show or hide cards on your dashboard using the new preferences button at the top of the page. This lets you tailor your dashboard to show only the items you use most. Khipu-style popups: We've brought the interactive popups from our Khipu visualisation to more places across Atlas. These popups are significantly faster than our previous popups and provide detailed, draggable information panels in the measurement details overview (all types), the results tab (traceroute and DNS), and QuickLook. DNS resolver details: When viewing DNS measurement results, you can now click on the info button in the new details column to see the complete DNS response (for all resolvers) in a dig-style format, including all flags and sections. Historical data archives for Khipu: Khipu can now pull archived IP2ASN, IXP, IP2Country, and ASN2Country data when viewing older measurements (back to Sept 2025). This means you get more accurate lookups based on the data as it was at the time of your measurement, rather than current data. You can configure how many archive snapshots to keep locally in your preferences. You can see the full list of what has changed in the release notes: https://atlas.ripe.net/docs/releases/website_index/2026-01-05 As always, we welcome your feedback and would love to know what you think.

Call for software project proposals (TU Delft)
by Giovane C. M. Moura 12 Dec '25

12 Dec '25

Folks, ## TL;DR: ``` if project_idea_exists and time_remaining <= 0: upload_to_students("https://sp.pages.ewi.tudelft.nl/site/") see_previous_year_project("https://ntpinfo.sidnlabs.nl") print("it uses RIPE Atlas") print("Deadline: Sunday March 15th 2026.") else: coffee.refill() ``` ## Longer version If you have a nice project idea but no time to develop, you could consider to "outsource" it to a group of 5 bachelor students to do that for you. Previous year example: we wanted a Internet.nl-like site for NTP, but we lacked CPU cycles do develop it. So we submitted a project proposal to TU Delft software project course[0], and students developed it[1], as an open-source project. We host a copy at SIDN Labs: https://ntpinfo.sidnlabs.nl. It uses **ripe atlas** to do real-time atlas measurements. The students presented it at both RIPE91[2] and ICANN84 meetings[3]. We would like to invite folks from the RIPE community to submit projects too. ## Who can submit it? * Anyone, can be from companies or academia * It does not have to be open-source, but students like open-source better -- it helps them to find jobs later ## What's your role going to be? * You'll be the _client_, you have to say what you need. * The students have a _coach_ and a supervisor to help make the technical choices ## What can you expect? * A group of 5 motivated second year Bachelor students. * The project will run from mid April to the end of June (roughly 10 weeks). * Each student will spend up to 320 hours working on the project (most of which will be development). * As a client company you retain the IP for the product that is developed by the students during the project. * The students retain the IP of the report they have to create about their project. If you have any questions, please let me know or the contact info at [0]. Thanks, /giovane [0] https://sp.pages.ewi.tudelft.nl/site [1] https://github.com/NTPinfo/NTPinfo [2] https://ripe91.ripe.net/programme/meeting-plan/sessions/17/ [3] https://icann84.sched.com/event/29QJv/ccnso-tech-day-1-of-4

Atlas UI update 2025-12-11, new LIR overview visualisation
by Stephen Suess 11 Dec '25

11 Dec '25

Hello Atlas Community, We have just released an update to the Atlas frontend, with a couple of new features and some fixes: LIR Overview - This new visualisation came out of work on our recently released Member Overview use case. The visualisation presents an interactive bubble diagram that shows Atlas probes and anchors within these LIRs' prefixes, as well as measurements targeting these prefixes. You can check it out here: https://atlas.ripe.net/statistics/lir-overview Health check banners - The Atlas team has done significant work recently on the backend to be able to better monitor the overall health of the system, and the UI will now be able to provide up to date specific warnings in a banner when loading the site, with links out to status page entries where appropriate. To see the full list of what is new, changed, or fixed, please visit the release notes here: https://atlas.ripe.net/docs/releases/website_index/2025-12-11 As always, we welcome your feedback. Please let us know if you have any questions, comments, or encounter any issues in the new update. Kind regards, Stephen Atlas UI

Re: v3 probe stuck with BADMD-APP
by Marek Zarychta 25 Nov '25

25 Nov '25

Hello, I have had recently the same problem like Radu described. The probe wasn't connecting with this message since 2025-11-07 09:45:52, so I have taken this probe to different ASN, but it didn't help. Today, after configuring the DNS servers in the original ASN to respond to queries coming from the probe’s temporary network, the probe was finally able to reconnect. It looks like the issue with DNS setting was a problem here. The probe was initially set to use static IP and IPv6 addresses. After changing a few weeks ago to dynamic ones it's still stuck with old DNS server settings. It's really hard to fix the USB issue with the probe using static addresses. The only working way was taking it to the network with working DHCP and/or IPv6 auto-configuration including RDNSS, plugging it without USB, waiting several minutes, plugging USB stick, waiting till it reboots, disconnecting from the network, and connecting back to the network for which static addresses were configured. Of course, if there were DHCP or RDNSS working in the original network, the troubleshooting would be far easier. Anyway, I have two requests for the RIPE Atlas operations team: - please ensure that DNS settings automatically switch to dynamic when changing a probe’s addressing mode from static to dynamic, - please allow users to change a probe’s addressing mode from static to dynamic even when the probe is currently offline. Cheers -- Marek Zarychta

Atlas UI update 2025-11-24
by Stephen Suess 24 Nov '25

24 Nov '25

Hello Atlas community, We have just released an update to the Atlas frontend, with new features, changes and fixes. Here are some of them: NEW: Member resources dashboard card and use case - We have a new feature for members, both as a dashboard card and a use case (https://atlas.ripe.net/use-cases/member-resources) Members will be able to see Atlas probes and anchors within their LIRs' prefixes, see measurements that are targeting those prefixes, and link to these objects. NEW: Probe detail results: traceroute comparison component - We have been working on a component for comparing traceroutes over time, and the first place we are rolling it out for testing is on the results tab of the probe detail page (for example: https://atlas.ripe.net/probes/1/results) When you click on a point and show traceroutes, this component will pull 12 hours of traceroutes on either side of that point and show a timeline of significant changes for comparison. NEW: Probe detail results: download data (csv/json) - On the same probe results tab, you now have a menu in the graph allowing you to download the data in csv or json format. NEW: Probe detail overview: show recently stopped measurements - You will now see a button in the probe detail overview not only for measurements currently running on the probe, but also for recently stopped measurements. In addition to the new items above, there are numerous changes and fixes present. For the full list, please see the release notes here: https://atlas.ripe.net/docs/releases/website_index/2025-11-24 We would love to know what you think. Please let us know if you have any questions, comments, or encounter any issues with this update or elsewhere in Atlas. Kind regards, Stephen Atlas UI

v3 probe stuck with BADMD-APP
by Radu Anghel 11 Nov '25

11 Nov '25

hi, one of the v3 probes i spread around the universe that is 12+ years old just had another USB stick die after a power failure. i have tried reviving it by replacing the stick (tried at least 3 different ones), but for some reason it does not work as when i previously replaced it. i also tried different partitioning on the 16/32gb sticks: one single partition fat32/ntfs/ext4, no partitions at all. the probe does not format the new stick or do anything with it except reporting it to the controller, i see "registrations" in the event log with info about the USB that is plugged in. after that it just keeps repeating the BADMD-APP SOS DNS query. no blinky light on the stick to show activity. tried leaving it for more than 8h with the new stick, tried plugging in the stick 10+ minutes after probe booted, tried booting with the fresh stick plugged in. no changes in behaviour. also replaced the power source/cable, that did not help either. is there anything else i can try to revive it? thanks!
