The APG undersea cable had a problem on December 26. This is the 3rd undersea fiber optic cable route in Vietnam that has had problems recently.

Previously, two other undersea cable routes, AAG and AAE-1, were reported with faults, which have yet to be fixed. Specifically, the AAE-1 cable encountered a shunt fault at a location close to the waters of Hong Kong (China). The AAG undersea cable has problems in two directions to Singapore and China.

Vietnam has 7 undersea fiber optic cable routes, besides terrestrial fiber optic systems. The problem with APG, AAG and AAE-1 has caused concern among Vietnamese Internet users.

A representative of a major Internet service provider (ISP) in Vietnam told VietNamNet that it is still not possible to estimate the impact of these incidents. However, this is not the first time that the undersea fiber optic cable routes connecting Vietnam to the world have had  problems.

Based on its experience in dealing with similar incidents before, the service provider said it would use other cable routes to ensure uninterrupted service delivery to customers.

A representative of another ISP in Vietnam confirmed with VietNamNet that the APG undersea fiber optic cable connecting Vietnam to the world is currently having problems.

According to the expert, network operators in Vietnam that use undersea fiber optic cables have all spread their bandwidth through many cable routes rather than through only one or two routes to minimize risks.

"In the last two years, we have doubled the international bandwidth traffic to prepare for the situation when undersea fiber optic cables have faults due to various reasons," a representative of an ISP said.

As soon as an outage occurs, bandwidth shortages will be compensated by reserves, ensuring the lowest impact on customers. 

Vietnamese ISPs have backup plans so Internet users in Vietnam do not need to worry that these incidents will cause interruptions and affect the transmission line.
