Asia-America Gateway

Asia-America Gateway

The Asia-America Gateway (AAG) is a 20,000-kilometre (12,000 mi) long submarine communications cable system, connecting South-East Asia with the mainland of the United States, across the Pacific Ocean via Guam and Hawaii. [1][2]

The cable is capable of delivering up to 2.88 Tbit/s (US-Hawaii & Hong Kong-South East Asia) and 1.92 Tbit/s (Hawaii-Hong Kong). The cable was ready for service on November 10, 2009.[3]

Development of the AAG cable system was funded, at a cost of $500 million USD,[2] by 19 partners: The Authority for Info-Communications Technology Industry of Brunei Darussalam, AT&T (USA), BayanTel (Philippines), Bharti (India), British Telecom Global Network Services (UK), CAT Telecom (Thailand), Telkom Indonesia (Indonesia), ETPI (Philippines), FPT Telecom (Vietnam), Ezecom/Telcotech (Cambodia), Indosat (Indonesia), PLDT (Philippines), Saigon Postal Corporation (Vietnam), StarHub (Singapore), Telekom Malaysia, Telstra (Australia), Telecom New Zealand, Viettel (Vietnam), and the Vietnam Posts and Telecommunications Group. The cable has landing points at the USA, Hawaii, Guam, Philippines, Hong Kong, Malaysia, Singapore, Thailand, Brunei and Vietnam.[1][4][5]


The cable has encountered frequent breaks and outages since it was made ready for service in late 2009. Most of the outages have been located at the intra-Asia segments between Hong Kong and Singapore, while the segment between Hong Kong and the Philippines seems to have fewer problems. The segments between the Philippines and the United States are quite stable.[6]

On July 15, 2014 the segment 18 km off the coast of Vung Tau, Vietnam was damaged, and the internet bandwidth to international destinations was disrupted. VNPT's Viet Nam Data Communications Company Deputy Director Nguyen Hong Hai, said that the time that it would take for repairing the cable had not yet been determined. On July 27, the line was mended, 3 days earlier than the scheduled date.[7]

On September 15, 2014 a segment of the cable between Vung Tau and Hong Kong was damaged, which was expected to cause network slowdowns in Malaysia, Singapore, Thailand, Brunei, Vietnam, Hong Kong, Guam and the Philippines. In early reports, the cable break was identified as being in the same area as the July 15 incident, off the Vietnamese shoreline near Vung Tau. A representative of Vietnam's FPT Telecom said that this incident was most likely caused by anchors from local ships dragging along the shoreline, and blamed the cable's poor technical design as a factor in the repeated breaks.[8][9] Later reports contradicted earlier reports of the break being off the coast of Vung Tau, stating instead that section S1I, off the coast of Hong Kong, had ruptured.[10]

Initially expected to be mended within the 20 days of the incident, repairs experienced a setback when a new rupture was found. The new break, 68 km off the coast of Hong Kong, was only 4 km away from the original one. A date of October 3, 2014 was given for full restoration of service, with repair operations continuing until October 5.[11][12]
