In the past few years, new standards have emerged in the DNS space, but we understand migrating a core component like DNS to adopt new standards can be difficult and challenging. As we prioritize future Windows work, we would like to know more about what customers like you are using to support your own DNS deployments. We have published the survey below to ask you a few questions that will contribute to that exercise.
Link to the survey
The survey is fairly short and anonymous (though we left a field for sharing your contact information if you would be okay with direct follow up). Thank you in advance for your responses; your experiences will help us focus on what you find most valuable in our future work.
