Hi

To extend the info on this one:

unattended-upgrades updated this package today, and caused the same issue for me, causing servers to stop resolving DNS internally. Rebooting after installing resolved the issue, suggesting the update itself is fine, but the process of updating breaks resolution.

After updating a server (without reboot), the internal DNS servers received odd queries of type TYPE20736 (no idea what that is)

21-Mar-2017 10:38:49.627 queries: info: client 172.16.x.x#49803 (host.internal.domain): query: host.internal.domain IN TYPE20736 + (172.16.x.x)

After rebooting said server, it starts querying normal type A records again.

I also run some authoritative DNS servers, and have seen the same query type from the public - suggesting that other servers out in the wild are experiencing the same issue!

21-Mar-2017 14:22:22.578 queries: client x.x.x.x#43836 (www.domain.com): query: www.domain.com IN TYPE20736 - (x.x.x.x)

I realize this is not directly related to the subject of this bug, but I think its relevant.

Cheers,
Michael
