Meta-information dumps for built-in measurements?
by Vasileios Giotsas 09 Nov '20

09 Nov '20

Is there any repository like https://ftp.ripe.net/ripe/atlas/measurements/ that contains meta-information about built-in RIPE Atlas measurements (the above repository contains meta-information only for public measurements)? I couldn't find anything similar in the new FTP repository at https://data-store.ripe.net/datasets/atlas-daily-dumps/ I guess using the API is an alternative but it would be more convenient to have such dumps Thanks, Vasileios

Responsive Probe Fluctuations
by Marcel Flores 05 Apr '19

05 Apr '19

Hi All, Noticed a funny little swing in probe responsiveness. It seems to have returned to normal, but was curious if anyone else had seen it. We do one-off measurement where we select all probes, usually the responsiveness rates look something like: 12743 Requested / 10147 Actually Participated (Taken from 18 March) But on 19 March we started seeing rates more like: 12914 Requested / 7852 Actually Participated Which continued until about 28 March, when it returned to about the previous levels: 12916 Requested / 9943 Actually Participated Something funny happen with the dispatching? Did anybody else see? -- *Marcel Flores, PhD* | Sr. Research Scientist research.verizondigitalmedia.com | AS15133 <https://www.peeringdb.com/asn/15133> p: +1 310.593.6880 e: marcel.flores(a)verizondigitalmedia.com 13031 W Jefferson Blvd. Building 900, Los Angeles, CA 90094

Probe not coming online anymore after firmware upgrade
by Annika Wickert 25 Mar '19

25 Mar '19

Hi everyone, I bought a new USB Stick for this probe as the old one was tagged as readonly etc.. https://atlas.ripe.net/probes/23913/ <https://atlas.ripe.net/probes/23913/> In the panel it says: 2019-03-21 14:50:02 UTC Probe firmware upgraded Your probe #23913 <https://atlas.ripe.net/probes/23913/> upgraded its firmware from version 3.3.8 to version 4960 But for some reason it is not coming online at all :(. Any idea what could be the issue? I also see no network traffic at all originating from the probe. Best, Annika

I have a group of students working on a research project to characterize certain aspects of DNS and HTTP interactions on the Web. To get a representative measurement, we need to resolve hostnames from top-1M websites from a large number of widely dispersed probes. So we need a large amount of credits and I was wondering if I could ask folks for help. My back of the envelop calculations suggest we are short of ~200M credits. I realize it’s a large amount, but we would take any help we can get and will conduct as credible measurement as we can with the credits we assemble!

Request RIPE Atlas Credit for Research
by 陆超逸 07 Mar '19

07 Mar '19

Dear all, Greetings! I'm a PhD student at Tsinghua University, China. Recently a large-scale measurement via RIPE Atlas is needed for my research. However, as a new user I don't have any credit to proceed, and unfortunately the time doesn't allow me to earn them by myself. So I'm here to ask for help. Is it possible for anyone generous enough to offer me some RIPE Atlas credits (like, a million)? My account at RIPE NCC is lcy17(a)mails.tsinghua.edu.cn. Many thanks for your help! Sincerely, Chaoyi Lu

Graphing packet loss
by Steve Hill 01 Mar '19

01 Mar '19

I've got some ping measurements set up and am trying to find a good way to visualise outages. The Latencymon tool obviously shows red shaded sections on the graphs for an outage, but they vanish when zoomed out a long way. A graph of average packet loss seems the obvious way of doing it, but it doesn't look like there's any way to get this from the Atlas website, sort of downloading the data and building my own tool to analyse it. Am I missing something obvious? :) -- - Steve
