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!

A system tag for DNS resolution of "other types"?
by Stephane Bortzmeyer 11 Nov '25

11 Nov '25

I see a probe (31874) which can resolve A and AAAA (and has system tags for that) but always SERVFAIL for TXT records. % blaeu-resolve --probes 31874 --type TXT ietf.org [ERROR: SERVFAIL] : 1 occurrences Test #136741617 done at 2025-11-08T16:31:22Z % blaeu-resolve --probes 31874 --type A ietf.org [104.16.44.99 104.16.45.99] : 1 occurrences Test #136741646 done at 2025-11-08T16:31:36Z (You can check with other domains such as ripe.net.) Suggestion: a system tag "Resolves TXT".

IXP Country jedi seems to be down
by Vasileios Giotsas 07 Nov '25

07 Nov '25

Hi all, It seems that the data endpoints for the IXP Country jedi website are down. The website itself (https://jedi.ripe.net<https://jedi.ripe.net/latest/AT/geopath/index.html>) is loading, but none of the graphs are loading, e.g. the https://jedi.ripe.net/latest/AT/geopath/geopath.v4.json is returning 404 (and all other json data paths) so the plots aren't loading. Just thought to bring it to your attention because these data are very useful. Best, Vasilis Giotsas

BIG Atlas UI update for 2025-11-06
by Stephen Suess 06 Nov '25

06 Nov '25

Hello Atlas friends, We have just released a pretty big update to the Atlas frontend, with lots of new features. Here are some of them: Probe Connectivity use case - Visualise Internet connectivity by analyzing RIPE Atlas probe connection states over time. This tool helps identify potential outages and connectivity issues across different networks and regions. Here is an example link showing a power outage in Chile earlier in the year: https://atlas.ripe.net/use-cases/probe-connectivity/?method=country&start=1… Khipu: export image and data - There is now an export button in the toolbar allowing you to export Khipu visualisations as pngs, and menu items for exporting your filtered or full measurement data source in either json or csv formats Khipu: multi term path filter - You can now use multiple terms in the path filter to further refine your path selection Khipu: country filter improvements - You can now filter by continent, search for a country, or invert your country selection Clone a measurement (from detail and listing pages) - You can now clone existing measurements (that are stopped and not system tagged) by clicking on a clone icon in the measurements listing page or next to the heading on any valid measurement detail page. This will open a new measurement form with all settings filled in except for timing. Measurement Form: duplicate definition - Within the measurement form itself, you can now duplicate a measurement definition to help copy similar configurations. Recheck DNS option (in measurement form and measurement detail manage tab) - This setting (on by default for periodic measurements that don't resolve on probe and are targeting a domain) will recheck the domain resolution every 24 hours and update the measurement. For the full list of what is new, has changed or been fixed, please see the release notes here: https://atlas.ripe.net/docs/releases/website_index/2025-11-06 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

31 Oct '25

Good day, reference https://atlas.ripe.net/khipu/134895113/ip I’d love to have the following to make it useful for my case: - Ignore “unsuccessful” not reaching the target In these case I do expect some connectivity issues, and those I’d like to look in, but I want to focus on the main issue in this case is RTT anomalies and routing issues so do want to ignire those. - focus on specific intermediate/IXP hops Ie. want to select some hops and have the radials around them only

soft probe sending out UDP frames
by Hans Mayer 30 Oct '25

30 Oct '25

Dear All, month ago I installed a soft probe. I have running ripe-atlas-common 5110, ripe-atlas-probe 5110, ripe-atlas-repo 1.5-3 on Debian 12 bookworm. These days I realised something where I need some explaination. When I look at the types of measurements then I would expect a certain amount of services that can go out. Like ping, traceroute, dns, tls, http and ntp. Now I saw that the probe sends out to about 89 different IP addresses ( IPv4 as well IPv6 ) UDP frames. I looked for a period of about a day. Each destination is probed with a specific port number. And this again and again all over the time. So each combination of destination IP and destination port is unique. The ports are high ports above 32k and as far as I can see there is never a reply. (Probably not necessary for UDP) There are a little bit more than 60 frames per hour. That's about 1 UDP frame per minute. Not to say, if I switch off the ripe-atlas.service this phenomena doesn't happen. Is there any explanation for this behaviour ? I can only imagine that these destinations are monitoring servers from ripe and my soft probe says: "hello, I am still alive ! ". ( I didn't dig into the UDP frame itself) Kind regards Hans -- The destination IP's are well distributed around the world.

Probe Reactivation?
by Cornelius Keck 29 Oct '25

29 Oct '25

My first-generation probe (1198) has been down for 2 or so years. Managed to get it going again inasmuch it pings the outside world. Current status at https://atlas.ripe.net/probes/1198/overview shows it to be abandoned, though it does SOS-ping. What could be done to change its state to active? Thx! -Cornelius

Fwd: Updated RIPE Atlas Terms & Conditions
by Karolina Bochenek 19 Oct '25

19 Oct '25

Dear Sulev-Madis, all, We amended the terms and conditions in line with applicable legal GDPR requirements and intellectual property law. Under GDPR, personal data cannot be processed without a legal basis, which in the case of RIPE Atlas, would be the individual’s consent. Also, a trade name may not be used without permission from its legitimate owner. To clarify, if consent or permission is granted, RIPE Atlas probe hosts may use personal data or trade names. Regions and cities that do not reveal the identification of individuals are also not personal data and can be used. Best regards, Karolina Bochenek RIPE NCC

Erroneous data in measurement 7000
by Filip Dobrev 07 Oct '25

07 Oct '25

Dear RIPE Team, I am a Master's student at TU Delft, currently working on a tool that uses RIPE data to reliably detect network outages. While analyzing the measurements, I noticed what appears to be incorrect data being reported. In particular, when counting the number of disconnected probes per country, I observed that many countries show a major outage on 23 April 2025, where nearly all probes were marked as disconnected for about an hour and a half before recovering. For example, in Spain (ES): 2024-09-10 12:58:10 UTC – 16:37:15 UTC (Duration: 3:39:05, Peak offline probes: 154) Happened across many(40+) countries 2024-09-17 10:37:04 UTC – 12:50:56 UTC (Duration: 2:13:52, Peak offline probes: 129) Happened across many(40+) countries 2025-04-23 09:39:27 UTC – 11:11:59 UTC (Duration: 1:32:32, Peak offline probes: 210) Happened across many(90+) countries The timing and duration of the April 23 outage are consistent across many countries. I’ve compiled more examples and raw data in this editable online notepad https://shrib.com/#Asa3ZLP3Xe. It seems that a large portion of probes were marked as disconnected, even though the raw measurement data indicates they were still actively sending and receiving information. It is important to note that such errors can be observed at other times for short periods of less than a minute - 20-05-2025, again across many countries. I would greatly appreciate your clarification on a few points: 1. What could explain this discrepancy? Is it a measurement issue or something related to RIPE’s internal systems? 1. Are all measurements potentially affected by this? For example, measurement 10310, during an outage in NMK on May 18, some probes showed no responses for a 30-minute window(possibly still timing out). Similarly, during the outage in Portugal on April 28, several probes had no data for multiple hours. 1. How trustworthy are the results from the measurements? 1. How long does it typically take for RIPE to detect and reflect a disconnected probe (or other events) in the API? 1. Different requests to root measurements take the same time, even though one is requesting 30 minutes and another is requesting 4 minutes of data. Is the overhead on Ripe's side the reason for this? Looking forward to your response! Best regards, Filip Dobrev

Debian trixie support for s/w probes?
by Andrew Elwell 16 Sep '25

16 Sep '25

Hi folks, Is there a plan to support debian stable 'soon' for the software probes? I know I could build from the git repo, but I'm lazy and would rather apt-get install it, but https://ftp.ripe.net/ripe/atlas/software-probe/debian/dists/ only has bullseye & bookworm. Hat tip to all involved tho, #1009903 seems to be chugging along happily (well, except that the hypervisor's due for an update & reboot shortly) Andrew

Notification on removal of system-ipv4-works && system-ipv6-works tags while connected
by Lukas Tribus 15 Sep '25

15 Sep '25

Hello, currently notifications are configurable for the event when a probe is disconnected; however when a probes remains connected but stops working (loosing or no having either system-ipv4-works and system-ipv6-works tags), we are blind. I have written a monitor script to query the API for this, to get this notification but I'm wondering if it would be possible to implement this at RIPE. The system-<AF>-works tags are already there. Software bugs and I guess HW issues can trigger hung probes that remain connected. It's hard to find out, unless one is specifically looking for it or specifically expecting the result of a single probe in a measurement. Lukas

tracemon false join
by Randy Bush 13 Sep '25

13 Sep '25

looking at TraceMON (for 128292864), it appears as if the traces for a bunch of sources converge at a common node before failing. but they do not. they fail at different points as one can see if one looks at the result details or at khipu. what am i misunderstanding here? this is very misleading to a novice. i see one madly clicking at the apparent point of failure desperately wanting its ip address. of course, i would never make that mistake :) randy

traffic graph
by Hans Mayer 05 Sep '25

05 Sep '25

Dear All, Based on the conversation about traffic here some days ago I took a look into my statistics. I looked at the dashboard from RIPE Atlas and I looked at netflow from the router for my probe. Both from the last 24 hours. This is the dashboard and this comes from netflow it is summarised for IPv4 in and out and IPv6 in and out. Not to be confused netflow shows bits and the dashboard bytes. There is another difference, netflow has 10 minutes intervals and it seem the dashboard has 3 minutes. But independent of that, the graphs should have some similarities. I am not worried about that because the traffic is below any perception. But is there any explanation ? It becomes funny when I switch to "Last Week" All the traffic is below the 0 KB line. Maybe it should be 10 KB and the "1" is not visible for some reason. Kind regards Hans

Suggestion to change "next" field in the result of a probes REST API query
by Shane Kerr 05 Sep '25

05 Sep '25

Hello, The REST API query to get probes is documented here: https://atlas.ripe.net/docs/apis/rest-api-reference/probes If you do a lookup which would return too many results, it sets the "next" field in the return, like this: -------------------------------------------------------------------- { "count": 55125, "next": "https://atlas.ripe.net/api/v2/probes/?page=2", "previous": null, ... -------------------------------------------------------------------- The idea is the REST API client will then make a call to the "next" URL and get the next batch of data; this is basic paging. There is no kind of transaction or anything, so the status of the probes can change between each call. This is fine since the status of the probes changes independently and you cannot count on their status really. One problem is that using "page" for this means it is possible to get the same probe twice. For example, if you are looking for "Connected" probes, and returning the probes in order of probe ID, and a probe that you have already returned becomes "Connected", then the answers will all shift up by one, and you will see the last probe twice. This can be avoided by instead of using "page" for the "next" field using whatever the sorting is for the returned values in the query. I think by default this is probe ID, so the "next" field could be: -------------------------------------------------------------------- { "count": 55125, "next": "https://atlas.ripe.net/api/v2/probes/?id__gt=101", "previous": null, ... -------------------------------------------------------------------- I suspect this would be faster on the back-end too. I ended up doing this logic on the client side and it works fine, although that is for a specific sorting order. It would be more complicated to do this for all orderings on the server side. Cheers, -- Shane

Non-Profit Arts Organization Seeking Credit Donations
by ADCIBC Tech Support 03 Sep '25

03 Sep '25

Hello All, My name is Ari Broad and I am the IT Director for a non-profit arts organization called The American Dance Competition, Inc. (www.adcibc.com) We have expanded our organization internationally and I need to do performance checks on the website in various countries abroad to ensure the site is working for international users as we recently found out our site is blocked in Mainland China, so I am doing my due diligence with other countries where we are touring. I have created a python script that will do this checking process for us (versus doing it manually through online tools which is time-consuming) that utilizes RIPE-Atlas, but it will not work because I have 0 credits on my account. I see that you have to contribute to the probes in order to get credits, I would love to contribute for science, but I do not have a desktop I could host this on. I reached out to RIPE-Atlas help and they suggested I reach out to this mailing list to ask for credit donations. *Here is a list of the tests I am attempting to run:*In these countries: JP,ES,DE,SE,DK,CH,GB,IT,CA,FR,NL,PL Run measurements on 3 ASNs per country. That's *36 site performance measurements. * I am not sure what the credit currency exchange is like, but if we could get enough credits to run these tests that'd be great. *But truly any amount of credits will help!* *If you have any amount of credits you would like to donate to us for our international site performance checks please send them to the recipient: adcibc.tech(a)gmail.com <adcibc.tech(a)gmail.com> * Thank you in advance for any donations we may receive. Best, *Ari Broad, M.S.* *(she/her)* IT Director ADC|IBC www.adcibc.com

Re: Notification on removal of system-ipv4-works && system-ipv6-works tags while connected
by Antony Gollan 03 Sep '25

Hello all, We use Brevo to send these emails primarily because it ensures deliverability and allows people to easily unsubscribe. This is important because big email providers have recently increased their penalties for potential spam, so we track bounces and unsubscribes to make sure the RIPE NCC stays within acceptable limits. It is not possible for us to turn off the tracking pixel in Brevo on our end, but we use it only to view the status of delivery, opens and unsubscribes. We are aware this tracking is not 100% accurate, but it gives us a general view of whether emails are reaching their recipients, which helps us to stay below the spam threshold. If you’d rather get a plaintext version of these emails from Brevo, some email clients provide an option to switch to the plaintext view. This will also block the tracking pixel. Regards, Antony Gollan Communications Team Manager RIPE NCC
