Request for RIPE Atlas Credits for PhD Research on Tor Path Measurements
by xt s 08 Sep '26

08 Sep '26

Dear all, Thank you again for the very generous support. I have now received more than enough RIPE Atlas credits for the planned experiments, so no further credit donations are needed at this point. I sincerely appreciate everyone who contributed. The support from the RIPE Atlas community has been extremely helpful, and I will make careful use of the credits for the research. Best regards, Xiaotian Suo PhD Student School of Cyberspace Science and Technology Beijing Institute of Technology

Request for RIPE Atlas Credits for PhD Research on Tor Path Measurements
by xt s 07 Sep '26

07 Sep '26

Dear RIPE Atlas community, My name is Xiaotian Suo, and I am a PhD student at the School of Cyberspace Science and Technology, Beijing Institute of Technology. I am working on a research project studying AS-level exposure and routing asymmetry on Tor client-to-Guard and Exit-to-destination paths. We plan to use RIPE Atlas traceroutes to calibrate and validate data-plane path-inference models. Our initial experiment is deliberately small. We plan to run approximately 20 one-off IPv4 ICMP traceroutes as a smoke test, followed by a paired pilot covering around ten AS-level endpoint pairs in both directions over three measurement rounds. The initial stage should consume fewer than 10,000 credits. If the pipeline works as expected, we would like to expand the study to additional AS pairs, probes, and time windows, and to construct an independent confirmation dataset. For this staged research campaign, I am therefore looking for up to 1,000,000 RIPE Atlas credits. Any partial donation would already be very helpful. Only safe, publicly reachable infrastructure will be used as measurement targets; residential or private end-user addresses will not be targeted. We also intend to make the measurement results available for research reproducibility where possible. My RIPE Atlas account for credit transfers is: xts1774(a)gmail.com Thank you very much for supporting this research and for maintaining the RIPE Atlas infrastructure. Best regards, Xiaotian Suo PhD Student School of Cyberspace Science and Technology Beijing Institute of Technology

Request for credits for reachability research
by Дмитрий Воропаев 07 Sep '26

07 Sep '26

Hello everyone, I’d like to study how Internet censorship in several countries affects the reachability of my small infrastructure. I deployed my first RIPE Atlas software probe a few hours ago and plan to deploy more probes in the future. However, I haven’t received any credits yet and would like to run some initial ping and traceroute measurements. If anyone has some spare credits to share, I would really appreciate it. My RIPE Atlas account email is: voropaevdmtr(a)gmail.com Thank you! Best regards,

Hi everyone, I'm investigating the effectivenss of new methods for increasing AS-level route security. I deployed a my own RIPE software probe recently, but have not gotten any credits yet. If anyone is willing to share 1-2M credits, it would really help me out! My RIPE account is benweintraub34(a)gmail.com. Thanks in advance!

Request for RIPE Atlas credits for latency research
by Ernst 31 Aug '26

31 Aug '26

Hello, I am running a small non-commercial latency study comparing OVHcloud AS16276 and Hetzner AS24940 connectivity to the public Bitfinex endpoint api-pub.bitfinex.com. I would like to run a 24-hour RIPE Atlas ping and traceroute measurement from a small set of probes in OVH LIM1 and Hetzner NBG1. My RIPE Atlas account currently has 0 credits. A small credit donation would be greatly appreciated. Around 10,000 credits would already be more than sufficient for this study. Thank you, Ernst

I’m doing a few one-off RIPE Atlas API tests to debug a reachability issue for my AS and need around 10k credits to do so. If anyone has a small amount to spare, I’d really appreciate a transfer to my Atlas account: tk(a)tkeith.com

Software Probe version 5130 released
by Trix Taiclet 14 Aug '26

14 Aug '26

Dear colleagues, We're happy to announce the release of the RIPE Atlas Software Probe, version 5130. This 5130 release contains the following main changes: - Fix NTP measurement offset (GH-130), a regression from the 5120 fix: it reported half the round-trip time instead of the clock offset - Move to new registration servers with ed25519 keys - Modernise the Debian apt repository (ripe-atlas-repo 1.6-1): deb822 .sources format and a Signed-By-scoped signing key, fixing the apt warnings on Debian 13 - Add the openwrt-hwprobe architecture as a common base for the next-generation hardware probe firmware - Measurement code - Add a minimum gap between NTP requests, 4000 ms by default (GH-114) - Send the NTP RIPE reference-id in network byte order, correcting it on big-endian architectures - Use the MAC address from the default-route interface - Use environment-specific SOS servers for SOS calls - Support both iproute2 and net-tools (reported by Paul Menzel, GH-147, GH-148) - Other - Change default SSH key pair algorithm to ed25519 - Pre-fill the probe's public key in the post-install registration URL - Fix RHEL and Debian packaging (dependencies, maintainer scripts, apt changelog) - Add libssl3t64 for Debian 13 (authored by Dreista, GH-139) - Fix the OpenWrt package build on 24.10 and 25.12 (GH-146) - Hardware probe fixes: boot from saved network configuration, reginit upgrade, update checksums - Fix typo in HTTP_POST_PORT configuration entry (authored by Firefishy/Grant, GH-141) - Wrap over-long help text in evtdig (authored by commodo/Alexandru Ardelean, GH-149) - Internal cleanups and CI changes Please note that NTP offsets reported by 5120 are incorrect. The reported round-trip time is unaffected. This is also the last release supporting Debian 11, given that its LTS will end on 31 August 2026. This release only applies to software probes. An update will be released for hardware probes once OpenWrt consolidation work is complete. The full release notes are available in the documentation: https://atlas.ripe.net/docs/releases/firmware_index/5130 You can find more information and instructions on the GitHub repository: https://github.com/RIPE-NCC/ripe-atlas-software-probe/ https://github.com/RIPE-NCC/ripe-atlas-software-probe/releases/tag/5130 Please let us know if you find any issues with this release.
