Another problem has occurred to the one of Vietnam’s essential submarine cable systems, resulting in sluggish Internet connection in the upcoming days.

The Asia Pacific Gateway (APG) communications cable system suffered an error at around 11:50 pm on Monday, slowing down international connectivity in Vietnam.

The issue was detected at the station in Chongming, China.

Following the incident, Vietnam Posts and Telecommunications Group (VNPT), a major Internet service provider in Vietnam, has redirected international traffic to other working cables that Vietnam is connected to as a temporary measure.

VNPT is now working with its global partners to fix the problem, which is expected to take about two to three weeks.

An error previously happened to the same cable system on February 27, affecting international connectivity in the Southeast Asian country.

It broke down at a spot 125 kilometers away from Hong Kong.

As of April 1, about 95 percent of the system’s capacity had been recovered.

APG, which runs about 10,400 kilometers underwater across the Pacific Ocean, connects Vietnam with mainland China, Hong Kong, Japan, South Korea, Malaysia, Taiwan, Thailand, and Singapore.

It can deliver a capacity of up to 54Tbps, the greatest of all networks in Asia.

This is the fifth problem that has occurred to the cable system since it was launched in 2016.

The other systems that are vital to Vietnam’s international connectivity are the Asia America Gateway (AAG), South-East Asia - Middle East - Western Europe 3 (SMW-3), and Intra-Asia (IA).

AAG is a 20,000-km submarine communications cable system connecting Southeast Asia with the U.S. mainland across the Pacific Ocean via Guam and Hawaii. It strikes land in Vietnam in the southern beach city of Vung Tau.

SMW-3 is the world’s longest cable system, which is 39,000 kilometers long, connecting Vietnam and 39 other countries through the landing point in central Da Nang City.

With a total length of 6,800 km, IA links Internet users in Vietnam, Singapore, the Philippines, Hong Kong and Japan.
