The Asia-America Gateway (AAG) undersea cable system was once again cut off in the waters off the southern province of Ba Ria - Vung Tau at 6.23am on Aug. 31, resulting in slow internet connections.

The cause of the cable severance is unknown and repair efforts are underway, but authorities can't confirm a completion date, as repair time is dependent on weather conditions.

This is the second time this year that the AAG cable system has been damaged - on March 8 a similar severance occurred resulting in internet paralysis within the country.

It took 20 days for the cable system to fully resume operations from the March incident, and maintenance was performed on the cables as recently as July./.
