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

Possibility to specify a POST payload?
by Lars Eggert 04 Sep '25

Hi, (Please let me know if there is a better way to make feature requests.) It would be great if it was possible to specify a payload for an HTTP POST when putting together an experiment. Thanks, Lars

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

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

Massive uptick in number of flows to/from probe
by Jenisch Ewald 03 Sep '25

03 Sep '25

Hi, Maybe coincidence with the update of the UI rolled out today, but we've seen a massive uptick in the number of flows going out from our probe up to a range of 120k flows/sec starting around 15:00 local time (CEST) Anybody else experiencing the same thing? Any ideas as to what's going on here? Thanks in advance for any clue, -ewald eingeschränkt/restricted

New RIPE Atlas Traceroute Visualisation Tool
by Stephen Suess 29 Aug '25

29 Aug '25

Hello Atlas friends, Recently we have been working on a new traceroute visualisation tool, and although we are still in early development, we wanted to release this version to the community to solicit feedback and opinions about it. This will help us focus on the items that are most important to the community as we work to finish it. You can test out this new visualisation on our beta-ui site <https://beta-ui.atlas.ripe.net/>, from any traceroute measurement detail page. Just look for the "TRACEVIS" link at the top of the page and click to access it. There is a labs article that describes the tool in some detail: https://labs.ripe.net/author/stephen_suess_1/new-prototype-ripe-atlas-trace… As always, we hope you find these features useful and we encourage your feedback. Kind regards, Stephen RIPE Atlas UI

Comparison of HW and SW Probes
by Richter, Robert 28 Aug '25

28 Aug '25

Hello everybody! Currently, I am investigating the possibilities of measurements using RIPE Atlas. Is there information about differences in the measurement results of HW and SW probes? My advisor said that I should rather not use SW probes, but I am not sure what the actual difference is, especially as SW probes often run on better hardware, compared to the HW probes. Could you point me to some resources on that topic? Best regards, Robert

Anchoring measurements from 7106 appear to be affected by a local proxy
by William Kanieski 28 Aug '25

28 Aug '25

Hi, all. I am a computer networks PhD student analyzing RIPE anchoring measurements for research purposes. While I was looking at traceroutes originating from specific anchors, I noticed that all traceroutes from Anchor #7106 only contained one hop, with no silent hops present. Upon further inspection, these singleton hops were actually the destination IP addresses themselves, and they had extremely short (<1ms) RTTs from 7106 even when they were supposed to be located on the other side of the globe. On the other hand, ping and traceroute measurements directed *toward* 7106 all seemed normal, with regular hop counts and RTTs that seemed to agree with reported geographical distance. I strongly suspect that 7106 is connected to a local proxy that is responding to outgoing ping and traceroute traffic on behalf of its intended destinations. As such, I wanted to bring some attention to this anchor so that other researchers might be aware of its status before trying to use it to conduct measurements. Regards, William Kanieski
