Thanks for publishing the results!

When you did the AAAA measurements, did you distinguish between the probe
not getting a response (e.g., if the dig command timed out) and the probe
getting a NODATA response?

[I tried to look at the raw data to answer this question, but wasn't able
to find out how to download it. I can see the probes that performed the
measurement, but not that the results were. Am I doing something wrong?]
