The junta began limiting access to the internet and confiscating satellite dishes as the information blackout worsened in Myanmar.
Fiber broadband service, the last legal way for ordinary people to access the internet, became intermittently inaccessible on several networks and authorities seized satellite dishes used to access international news broadcasts.
Protests against the February 1 coup that ousted the elected government of Aung San Suu Kyi had continued on Thursday despite the killing of 11 people by security forces a day earlier.
MBT said its service was halted by a break in the line between Yangon and Mandalay, the country’s two biggest cities, but internet users had been complaining for the past week of major slowdowns in the services.
The junta has gradually throttled down internet service since the coup.
It initially imposed a largely ineffective block of social media such as Facebook and then cut mobile data service, the most common way of connecting to the internet, but only at night.
As the junta increased its use of deadly force against protesters it also imposed a total ban on mobile data use.
The use of satellite television as a source of information also appeared to be under threat.
In Laputta and other towns in the Irrawaddy Delta southwest of Yangon, local government vehicles announced over loudspeakers that it was no longer legal to use satellite dishes and that they must be turned in at police stations.
Police also raided shops selling the dishes and confiscated them.
Since the coup, all non state-owned daily newspapers have stopped publishing and online news sites have come under severe pressure.
Five popular independent news services had their operating licenses revoked in early March and were told to stop publishing and broadcasting on all platforms, but mostly defied the orders. Other agencies have been sued over their coverage.
