The site thepresidency.gov.za was hacked by unknown people on Saturday morning.
Users trying to access the site where statements from the South African presidency can be found were greeted by a notice saying: "Hacked by Black Team. Sahara is Moroccan. And Morocco is ur Lord! (sic)"
"We can confirm interference with the Presidency website. Our technicians are currently investigating the incident," Khusela Diko, Cyril Ramaphosa's spokesperson told News24.
Diko said they do not have any information at this point as to who was responsible.
The site was earlier disabled by government after it was made aware of the hacking. It was up and running Saturday afternoon.
The Citizen reported in August 2017, hacktivists operating under the Anonymous banner targeted government websites.
Anonymous had also targeted other websites earlier in the year such as the one belonging to public broadcaster, the SABC.
