Internet access was down again in Iran after a brief restoration of limited services, a monitor said.
"As of internet shutdown hour 240, traffic levels have fallen after a brief, heavily filtered restoration of select Google and messaging services in Iran," Netblocks said on X.
"During this time, some Iranians were able to give updates detailing the severity of the crisis on the ground," it added.
It had earlier reported some internet access had been restored in Iran 238 hours after authorities imposed a shutdown on January 8 over mounting protests.
