Meanwhile, the APG fiber optic cable has a problem and has completed the error correction.
In June, up to 2 out of 5 undersea cable routes in Vietnam had problems, affecting the speed of accessing foreign websites in Vietnam. One of the two lines completed repairs on June 11, while the other line will not be completed until at least next month.

Due to the complex structure and passage of the seabed, repair of fiber optic cables can take weeks. Illustration. Specifically, the APG fiber optic cable had a problem since May 11 near Hong Kong. The cause of the fault was determined to be a shun fault. The repair process of this cable route lasted 5 days, during which the entire service to and from Hong Kong, China of APG project member partners was interrupted. On the morning of June 11, a representative of an Internet service provider (ISP) confirmed that the error of the APG fiber optic cable had been fixed. For the AAE-1 route, the incident on May 25 was determined to be a broken cable. The incident partially disrupted the carrier’s service to Hong Kong. According to the announcement of the company in charge of the AAE-1 cable route to Vietnamese ISPs, it is expected that the repair time for this cable line will last from June 22 to July 13. The two cable lines mentioned above are the ones with large capacity. The APG route, with the investment of four Vietnamese carriers, VNPT, Viettel, FPT and CMC, has been in operation since December 2016. With a maximum bandwidth of 54 Tbps and a length of 10,400 km, the APG route passes through many Asian landing points such as China, Hong Kong, Taiwan, Japan, Malaysia, Singapore, Thailand and Vietnam. Meanwhile, the AAE-1 line has been in operation since July 2017, with a length of 25,000 km and a total capacity of 40Tb/s. This cable route has the role of improving quality towards Europe and the Middle East as well as providing additional capacity and redundancy towards the connection direction to Hong Kong and Singapore. According to representatives of ISPs, when an undersea cable problem occurs, the network operators must navigate through other fiber optic routes or other directions of the route that is having trouble. Specifically, Viettel has routed and supplemented traffic for TGN-IA, APG routes to Singapore and AAE-1 to France. Meanwhile, CMC Telecom increased capacity via cable direction across Southeast Asia (A-Grid), connecting Internet from Vietnam through Cambodia, Thailand, Malaysia and Singapore. VNPT navigates and loads other cable directions that are operating stably such as CSC, AAG, IA, SMW3.
