Talking to ICTnews on the morning of December 16, a representative of an Internet service provider (ISP) said that from December 13, the Asia Pacific Gateway (APG) international undersea fiber optic cable had problems in the connection direction. to Hong Kong (China). This is one of the five main cable routes connecting the Internet from Vietnam to the world.
“Currently, the cause of the incident on the APG undersea cable has not been determined. This incident has a relatively large impact on Internet connections from Vietnam to international routes on the route, with the loss of network traffic due to the impact of this incident is estimated at 1TB”, the ISP representative said.
The APG international undersea cable route was officially put into operation in mid-December 2016. APG has a length of about 10,400 km, is located underground in the Pacific Ocean, with the ability to provide a maximum bandwidth of up to 54 Tbps. The cable route has connection points in China, Hong Kong (China), Taiwan (China), Japan, Korea, Malaysia, Singapore, Thailand and Vietnam.
APG cable has the participation of investment from Vietnamese carriers VNPT, Viettel, FPT Telecom, CMC Telecom and is considered as a cable route that contributes to bringing a stable transmission line with a larger capacity for Internet users in Vietnam. .
It is worth mentioning that the APG undersea cable has just finished fixing the problem that occurred at the end of October on the S3 segment on November 27. Thus, just over half a month, this cable route encountered a problem.
Not only that, at the moment there is still another undersea fiber optic cable, Asia America Gateway (AAG), which is also having problems, has not yet restored the connection on the route.
AAG is an undersea fiber optic cable that directly connects Southeast Asia with the US, officially put into operation in November 2009. The countries and territories that the AAG submarine cable route passes through include Malaysia, Singapore, Thailand, Vietnam (the cable branch turns into Vietnam with a length of 314km, the landing point in Vung Tau), Brunei, Hong Kong (China) ), Philippines and the United States (Guam, Hawaii and California).
During 12 years of operation, the AAG undersea fiber optic cable route has encountered many problems or been maintained many times, making the communication and information exchange of overseas Vietnamese users on the route such as web services, email, video , social networks… are slow.
For the third time this year, AAG had an incident on the evening of October 22, causing a loss of all traffic from Vietnam to international routes on the route. At that time, the cable management unit expected the problem to be repaired by mid-December.
However, in the new information announced to ISPs in Vietnam, the plan to fix errors that occurred on October 22 on the AAG undersea fiber optic cable has been delayed. Specifically, it is expected that the error on the cable branch connecting to Singapore will be fixed from tomorrow, December 17 and completed on December 23. After that, the error on the cable branch connecting to Hong Kong (China) will be fixed during the period from December 23 to January 3, 2022. At that time, the transmission channels on this undersea cable route will be completely restored.
In the context of two undersea cable routes having problems at the same time, network operators also face certain difficulties in ensuring the quality of international Internet connection services for customers. However, because they are familiar with situations where undersea cables have problems, as soon as they receive the information, network operators will redirect traffic to other undersea cable routes such as IA, AAE-1, SMW-3 and other undersea cables. land cable direction.
ICTnews will continue to update information on the progress of repair and troubleshooting on 2 submarine cable lines AAG and APG.
