I once setup a measurement of DNS UDP to see if the number of timeout increase due to large response. The answer is yes. But I wonder if the timeout is no answer after three times of retries or also includes TCP fallback.
The Atlas DNS test apparently tries only once, and, by default, does not fallback to TCP. (Source: tcpdump.) I don't think tou can ask for several tests. (Source: <https://atlas.ripe.net/docs/api/v2/reference/#!/measurements>)
