Unlike most messages where zonemaster-engine has received a response and is able to critique what it receives, and can thus reasonable assert that what it got was what the server sent, when zonemaster-engine doesn't receive a response, it doesn't actually know if the server didn't receive the request, didn't send a response, or if the response was lost somewhere along the way.

It would be better to say:

Did not receive response to query for X via Y from name server {ns}

query for X via Y could be:

• NS queries over UDP
• NS queries over TCP
• SOA queries over UDP
• any queries over UDP
• NS queries over TCP
• any queries over TCP
• an SOA query

name server could be:

• name server
• SOA MNAME name server
