We did some measurements on the round-trip (RT) values of DNS queries for SOA (Start of Authority) records from our RIPE Atlas probes, over both UDP and TCP.

When we experienced an occasional operational issue with the data returned by one of our name servers, we wanted to verify DNS responses from a number of widely distributed measurement points (vantage points). RIPE Atlas was just the right service to provide us with the necessary raw data.
