DNS has been contracted to implement DNSSEC for the ZA zone by ZADNA, and the SLDs by ZACR (co.za, net.za, org.za, web.za).
The project began on 22 August 2016 and the estimated completion date is the 14th of April 2017.
The full project plan can be found here: DNSSEC -ZA & SLDs Project Plan
The plan includes time allocated for extensive testing due to the large size of the zones being signed.
