The Asian American Gateway Submarine Cable (AAG Submarine Cable) system is one of the four submarine cables in Vietnam and the largest one.

The Asian American Gateway submarine cable system is one of the four submarine cables in Vietnam and the largest one. The Asian American Gateway Submarine Cable System is a submarine communications cable system connecting Southeast Asia to the continental United States. The total value of $560 million AAG submarine cable system is 20,000 kilometers long. It connects Malaysia, Singapore, Thailand, Brunei, Darussalam, Vietnam, Hong Kong, the Philippines, Guam, Hawaii and the U.S. West Coast.

The system has failed several times in the Vietnam section since it was put into operation in 2009. The submarine cable encountered a failure on June 22, as new problems were encountered in the repair, and finally the repair of the AAG submarine cable was completed on July 17. And two days after the repair was completed, the AAG submarine cable encountered failure again.

According to the report, this time the fault was mainly detected on the SH1 branch, which is about 107 kilometers away from Tourton in southern Vietnam.

The problem could affect up to 15 percent of the total connection capacity from Vietnam to international destinations, especially Singapore and Hong Kong.

And according to the Vietnam Internet Association, the failure of the AAG submarine cable will also affect users of the country's 3G and 4G networks as well as international social network users.

The exact cause of the outage could not be determined yet. But after the outage was discovered, Internet service providers have taken necessary measures to minimize the negative impact on users.

Vietnam's international connectivity relies heavily on AAG as well as other submarine cable systems including APG, SMW3, IA and AAE-1.
