The Asia Direct Cable (ADC) international undersea cable route will be officially put into commercial operation by 2023 after completing the landing, Deputy General Director of Viettel Solutions Doan Dai Phong said on April 19.

The Asia Pacific Gateway (APG) undersea cable, which connects eight countries and territories in the region, is facing problems with its S1.7 section, about 910km from Southeast Asia.

Three international undersea cable lines that make up the majority of Internet connection capacity from Vietnam to the world have encountered problems, resulting in sluggish Internet speed across the country, according to operators.

The Asia-Africa-Europe 1 (AAE-1) undersea fiber optic cable had a problem on the S1H section on September 4, affecting internet connection from Vietnam to Singapore.

International internet traffic and speed in Vietnam have been back to normal after repairing work on the Asia America Gateway (AAG) undersea cable was completed.

Repairs to the Asia Africa Europe 1 (AAE-1) undersea fiber optic cable will be delayed to July 1 and expected to complete six days later, according to the managing board of the cable.
