The social network began to go dark in the nation of 200 million, the result of an escalating fight between Elon Musk and a Brazilian judge over what can be said online.
X began to go dark across Brazil on Saturday after the nation’s Supreme Court blocked the social network because its owner, Elon Musk, refused to comply with court orders to suspend certain accounts.
The moment posed one of the biggest tests yet of the billionaire’s efforts to transform the site into a digital town square where just about anything goes.
Alexandre de Moraes, a Brazilian Supreme Court justice, ordered Brazil’s telecom agency to block access to X across the nation of 200 million because the company lacked a physical presence in Brazil.
Mr. Musk closed X’s office in Brazil last week after Justice Moraes threatened arrests for ignoring his orders to remove X accounts that he said broke Brazilian laws.
X said that it viewed Justice Moraes’s sealed orders as illegal and that it planned to publish them. “Free speech is the bedrock of democracy and an unelected pseudo-judge in Brazil is destroying it for political purposes,” Mr. Musk said on Friday.
In a highly unusual move, Justice Moraes also said that any person in Brazil who tried to still use X via common privacy software called a virtual private network, or VPN, could be fined nearly $9,000 a day.
Justice Moraes also froze the finances of a second Musk business in Brazil, SpaceX’s Starlink satellite-internet service, to try to collect $3 million in fines he has levied against X. Starlink — which has recently exploded in popularity in Brazil, with more than 250,000 customers — said that it planned to fight the order and would make its service free in Brazil if necessary.
Mr. Musk and Justice Moraes have been sparring for months. Mr. Musk says Justice Moraes is illegally censoring conservative voices. Justice Moraes says Mr. Musk is illegally obstructing his work to clean up the Brazilian internet.
