SEOUL >> Parts of Southeast Asia are suffering slow Internet connections after an undersea cable linking the region to Hawaii and the U.S. mainland was cut earlier this week. 

Viettel Mobile, Vietnam’s largest mobile service operator, said Wednesday that repairing the broken cable, located in the Vietnamese section of the 12,427 mile system, will take from three weeks to one month and depends on weather conditions. 

The cable is part of the Asia-America Gateway linking Southeast Asian countries with the United States through Guam and Hawaii. The cause of damage was unknown. 

Military-owned Viettel said it has transferred its international Internet traffic to other cable networks. A Vietnamese news report said Internet traffic between Vietnam and Hong Kong, Singapore, Japan and the U.S. has been slowed.
