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?

Hi Atlas people,

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/
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:
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,
