Vietnam grapples with Internet cable problems

Sluggish Internet connectivity caused by problems with cross-sea cable systems has become a regular annoyance in Vietnam, and users are running out of patience.

At 7:20 am on October 12, the Asia America Gateway (AAG) cable network suffered a problem at its landing point in Hong Kong, signaling another period of slow connection speeds for Internet users in Vietnam.

The 20,000-kilometer system provides one of Vietnam’s lifeline Internet gateways to the world by linking it with other Southeast Asian countries and with the US across the Pacific Ocean.

The problem was by no means the first experienced by the AAG, which has one of the largest capacities out of those that Vietnam is connected to.

Since its launch in 2009, the AAG has experienced repeated problems, with two ruptures in 2014 and four cable cuts in 2015.

Vietnam’s Internet was also impeded between March 3 and 18 last year because of a power leak, according to local tech news website ICTNews.

As many as four separate problems have been reported with the AAG so far in 2017.

AAG and other submarine cable systems, including the Asia Pacific Gateway (APG), Intra Asia (IA) and South-East Asia - Middle East - Western Europe 3 (SMW-3) cables, are responsible for 90% of Vietnam’s international connections.

The APG system, which had been expected to be a reliable alternative to the AAG when it was put into use late last year, turned out to be a disappointment  after a rupture was reported in June along a section connecting the central city of Da Nang with the US, Japan and Hong Kong.

In a rare incident in August, all three submarine communications cables crucial to Vietnam’s international connectivity – IA, SMW-3 and AAG – came down with problems simultaneously, causing global connection from Vietnam to be slowed for over a month.

The root of the problem

According to Nguyen Manh Hung, chairman of Vietnam National Posts and Telecommunications Group (VNPT), recent problems with Internet cables are not to be blamed on faulty designs but rather on their locations.

As most of these cables make their landing points in Hong Kong or Singapore, they can be subject to constant disturbance caused by large vessels that frequent the busy ports, leading to ruptures, Hung explained.

Other possible explanations for repeated issues include anchors dropped by ships out at sea and natural geological fractures, he added.

“As for the AAG system, the developer must take some responsibility for not having conducted careful enough surveys of the network map to allow such problems to recur so frequently,” one leader of an Internet provider in Vietnam said on condition of anonymity.
