The internet services in Sudan are now “severely disrupted with further cuts observed,” according to an update from internet monitor NetBlocks.
The service disruption from 4:30 am UTC (12:30 am ET) manifested “in a telecommunications blackout for many,” NetBlocks said in an updated tweet on Monday.
Earlier, NetBlocks had reported an internet disruption with “national connectivity at 34% of ordinary levels” in Sudan.
A source in Khartoum confirmed to CNN that internet services remain unavailable and calls are not going through for some.
Observers on social media Monday raised alarm that the internet disruption was taking place as demonstrators gathered at the military headquarters in Khartoum.
The last time the internet was cut off in Sudan was amid a violent crackdown on protesters on June 3, 2019, when security forces killed more than 100 people gathered at a sit-in near the army headquarters. The internet shutdown continued for weeks, with activists saying that it was part of efforts by the ruling military council to roll back gains by demonstrators that had forced former president Omar al-Bashir.
