Per the Government Gazette of South Africa, Vol 657, 26 March, section 5.1.4:
All internet sites operating within .za DNA top level domain name must have a landing page with a visible link to www.sacoronavirus.co.za
We would like to extend our help to any businesses who need to implement this on their website like we have on ours. We added a simple message at the top of our website to accomplish this.
Please reach out to [email protected] and we would be happy to assist you with this. It will only cost you R50.
