Hi, I have two questions regarding probe selection for UDMs.
When I specify for example that I want to run an ongoing measurement on 250 probes in the "WW" region, will these probes remain the same throughout the lifecycle of the measurement (unlimited) or will these be somehow randomized every time the measurement is run?
Secondly, I am wondering about even spread of probe location in doing such a measurement. For instance I am as much interested in results from regions that have only a few probes, as I am interested in results from those regions that are better served. When I look at the results so far of a test measurement, it appears that I'm receiving results from 35 probes in US, but only 3 from FI and none from NO. The latter surprises me a bit since there are 100 probes reported in NO, so why aren't there any results from those coming back? The main reason for this is that when you specify only WW the only criterion to pick a probe is how busy it is in terms of how many measurements probes is assigned. We don't try to make any balance (country/region/ASN/prefix) except how busy is it and which controller

While I understand that countries with more probes will likely yield more results, I am wondering if there is any method to get a better "country-balanced" result for measurements ran in "WW".
I am afraid not at the moment. But, maybe there is something to consider for the future since I think other people have request it and we have internally discuss about it.
Thanks,
