Sadly, no bells are ringing. I looked at the obvious code, and can't see 
any obvious problems. The code which maps query domain onto servers )in 
src/domain-match.c) hasn't changed since 2021/2022 apart from 
b087cf4a6c3dd4c323a099770a44c24812381bf4 which looks unlikely as a culprit.

Logs would be useful.
