Question 4 ("What types of DNS resolution errors have you encountered most frequently?") has NXDOMAIN as one option, which implies that NXDOMAIN counts as a resolution error.

But of course, it's not a resolution error, but a valid outcome of a successful resolution.

Before reaching this question, I had selected "rarely" for question 3 ("How often does your organization encounter DNS resolution errors?").

With the knowledge from question 4, the only valid answer for question 3 however seems "daily", or even "all the time" (which is not an answer option).

Including NXDOMAIN as a resolution error will lead to biased results. For example, many people may select seeing this "daily", which may lead to a publication saying that "DNS resolution errors happen all the time", which is vastly inaccurate.

So, unfortunately, I aborted the survey at this point, as it is not well-defined, and I did not want to increase sample size in this case.

Best,
Peter
