# DNS Server Driver Support Matrix

This info should be maintained along with the list of current driver maintainers responsible for the “Non Integrated” backends. The upkeep of this list will fall on the PTL or his/her delegate.

Should a backend’s grade be in dispute, it falls on the current project PTL to make the final decision after listening to all sides concerns.

Grades

Grade | Description
--- | ---
Integrated | Tested on every commit by the OpenStack CI Infrastructure, and maintained by designate developers as a reference backend
Master Compatible | Tested on every commit by 3rd party testing, and has a person or group dedicated to maintaining compatibility on a regular basis
Release Compatible | Not necessarily tested on every commit, but has a maintainer committed to ensuring compatibility for each release
Untested | All other backends in the designate repository
Failing | Backends that were previously “Compatible”, but tests are now failing on a regular basis.
Known Broken | Backends that do not work, and have been broken with no sign of any fixes
Experimental | Backends that are under development, and may change at any time
Deprecated | Backends have been superseded, and will be removed in the future
End of Life | A backend that has reached it’s end of life and has been removed from the code.
