Ten hours after it was warned, the SABC was hacked over alleged censorship.
Anonymous Africa, under the handle @zimforthewin, tweeted: "Journalists, if you are bored. Tomorrow, at around lunch time, the SABC will be on the receiving end of largest dDos attack to hit SA ever."
The group tweeted earlier that the hack was to punish the national broadcaster for "censorship".
The group taunted SABC chief Hlaudi Motsoeneng: "@zim4thewin @SABC_COO Here is looking at you sunshine ;) todays downtime is caused by your crimes against the people of SA."
The SABC sites remained down for most of the afternoon, with the group later tweeting: "Every time @SABC_COO censor the SABC more, we are going to come back, and keep hitting harder until @SABC_COO cannot get up again. #Anonops"
The hack comes in the wake of the broadcaster's decision not to screen footage of protests.
SABC spokesman Kaizer Kganyago confirmed the hack and condemned it "in the worst possible words".
He said as far as he knew, all SABC sites were affected and it was the first hack of this scale in recent memory.
