## Operation
On launch, the BindBackend first parses the `named.conf` to determine which zones need to be loaded. These will then be parsed and made available for serving, as they are parsed. So a `named.conf` with 100.000 zones may take 20 seconds to load, but after 10 seconds, 50.000 zones will already be available. While a domain is being loaded, it is not yet available, to prevent incomplete answers.
