Hi Johan,
Thanks for you information. It works follow you advice to find these built-in measurement. But I need more probes (maybe all of them, or large set) and RTT data for just one day. It is impossible for me to do it manually. Is there any tool for me to select a group of probes or measurements in the rtt-fixed map?
I think you’re mis-understanding how the built-ins work. These measurements do run on all the probes and therefore have the data for all of the probes. In the download tab, you can then select the day you want and download the results. For instance: https://atlas.ripe.net/api/v2/measurements/1009/results/?start=1545350400&stop=1545436799&format=json This gives you all the results for all the probes for 21 December 2018. You can of course also select a day in the map view itself using the time travel slider. Again, be aware that these results are huge so you should use curl or our Python libraries to get and process these results. You can find all the RIPE NCC tools here: https://github.com/RIPE-NCC <https://github.com/RIPE-NCC> The specific ones you want are: https://github.com/RIPE-NCC/ripe-atlas-tools <https://github.com/RIPE-NCC/ripe-atlas-tools> https://github.com/RIPE-NCC/ripe.atlas.sagan <https://github.com/RIPE-NCC/ripe.atlas.sagan> https://github.com/RIPE-NCC/ripe-atlas-cousteau <https://github.com/RIPE-NCC/ripe-atlas-cousteau> Let me know if I answered your question. If not, I will try to help you further. Kind regards, Johan ter Beest

Hi Atlas people,
<I did not receive mails from this list months ago. I hope it still works.>
I’m writing to ask about the Data repo in the intnernet maps. For example I would like to study the DNS root RTT statistics in this page : https://atlas.ripe.net/results/maps/rtt-fixed/ <https://atlas.ripe.net/results/maps/rtt-fixed/>
Where and How should I get the access to this data.
These maps are based on the built-in measurements that are running on all the probes. You can go to any probe and then look at the built-in tab to see the measurement IDs for these built-in measurements.
You can then go to the measurement page for the desired measurement and download the results for the timeframe that you want. For instance:
https://atlas.ripe.net/measurements/1009/#!download <https://atlas.ripe.net/measurements/1009/#!download>
This is the built-in Ping measurement towards a.root
Remember that the results for these measurements are huge so be careful in selecting your timeframes.
Let me know if you need any more information.
Cheers, Johan ter Beest RIPE Atlas Team
Best regards, Davey
