I was observing random flapping for services when browsing for a longer time. I did some debugging and digging. The root cause: when looking for address records to refresh we didn't normalize the host-name to lowercase, but we store those records keyed by the host-name in lowercase.
In a query example one could observe the following:
I've tracked it down to A / AAAA records not being refreshed, due to the root cause described above.
