Reloaded DNS configuration; removed node XXXXXX

Can external DNS changes cause a node to be removed from MAAS?

We lost a large group of servers, and the only evidence of it we can find is this log entry

2019-06-06 11:44:39 maasserver.region_controller: [info] Reloaded DNS configuration:
* removed node nodename1
* removed node nodename2
* removed node nodename3
* removed node nodename4
* removed node nodename5
* removed node nodename6
* removed node nodename7
* removed node nodename8

Normally if we see a node removed, we also see an API entry for DELETE.

For the above example, there was no accompanying API DELETE.

Disregard - We found the problem and will post separately about it
