Comment 2 for bug 1714088

In previous versions, like Mitaka, when a polling mechanism was used for integrating dns with neutron,
we had a shared network configured with only one zone under 'admin' project, and it was used by all projects when creating instances. So all instances would be reachable by their domain name, no matter what project they were created in.

However, after upgrading to Ocata we found that the new mechanism (that neutron notifies designate of new machines), does not notify if the zone is not present in the project the instance is created in.

I'm reopening this as a bug, as it is a deterioration of a previous mechanism that worked, and now doesn't.
