Renesys Corp., a company that maps the pathways of the Internet, said it could not confirm whether the blackout was government-orchestrated. But the outage recalls a similarly dramatic outage in Egypt, Sudan's neighbor, when authorities shut off Internet access during that country's 2011 uprising.
"It's either a government-directed thing or some very catastrophic technological failure that just happens to coincide with violent riots happening in the city," said senior analyst Doug Madory yesterday. He said it was almost a "total blackout."
A police statement said at least three people have died in three days of rioting over the lifting of fuel subsidies two in the town of Wad Medani south of Khartoum, and one in the Omdurman district of the capital.
In northern Khartoum, Sudanese security forces fired tear gas to disperse dozens of protesters who demonstrated and torched a police station.
Yesterday's protests took place in several areas of Kadro district, 25 km from the capital's city center, where protesters blocked roads using lengths of pipe and burning tires. They also attacked a police station.
The rioting started after Sudan's government decided to lift the subsidies, immediately doubling prices of gasoline and fuel.
The semi-official Sudan Media Center yesterday quoted Gezira governor Al-Zubair Bashir Taha as saying that aside from police stations, riots there targeted power and gas stations, banks, shops and private property.
Police are tracking down the "saboteurs," he said.
The SMC also quoted the deputy head of the Sudanese parliament, Samiya Ahmed Mohammed, as saying she hopes the "opposition understands the measures with objectivity."
An initial attempt by the government to cut subsidies sparked similar protests but they were quelled by a heavy crackdown on protesters, activists and journalists.
Al-Bashir is wanted by the International Criminal Court on allegations linked to the conflict in Sudan's western region of Darfur where an estimated 300,000 people have died since 2003 due to fighting between government-backed tribes and rebels.
