With a length of 20,191 km, the AAG route connects Southeast Asia with the US. This cable route has been in operation since November 2009, passing through Malaysia, Singapore, Thailand, Vietnam, Brunei, Hong Kong (China), the Philippines and the United States (Guam, Hawaii and California).

In 2021, the AAG line had problems on June 22 and July 19, which were fixed on July 12 and August 20, respectively.

However, on August 11, a new error on the S1B segment from Hong Kong to Singapore of the AAG line was detected. The incident has affected Internet speed in Vietnam since then.

The repair was delayed twice on September 22 and October 6 and until 10pm on October 10 it was fixed.

However, the error on the AAE-1 submarine route has not been fixed yet, causing Internet service disruption in Vietnam. According to ISPs, the incident will be repaired in early November.

Asia-Africa-Europe 1 (AAE-1) is a 25,000km submarine cable from South East Asia to Europe across Egypt, connecting Hong Kong, Vietnam, Cambodia, Malaysia, Singapore, Thailand, India, Pakistan, Oman, the UAE, Qatar, Yemen, Djibouti, Saudi Arabia, Egypt, Greece, Italy and France.

The AAE-1 cable system is designed with 100Gbps technology, with a designed trunk capacity of more than 40 Tbps on 5 fiber pairs. It has been in operation since July 2017, with 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 (China), Singapore.

On September 4 and September 7, errors were reported on two segments of the S1H branch. The incidents disrupted Internet connection capacity from Vietnam to Singapore and Europe. This is the second time this year that the AAE-1 cable has had problems. The first occurred on May 25, which was fixed on July 12.

This is not the first time that errors have occurred on both submarine cables at the same time. However, this time the incidents happened at the beginning of the new school year, when millions of students are studying online under the impact of the Covid-19 pandemic. Some users complained that their operations have been seriously affected due to poor Internet speed and network quality.

The cable management unit on September 13 informed Internet Service Providers (ISPs) in Vietnam that the incident would be fixed from November 2 to 14. However, according to updated information, the repair will be completed on November 6, a week earlier than the initial plan.

Hanoi faces waste storage crisis

Published

on

Xuan Son Landfill in Hanoi’s Son Tay Town stopped receiving waste from October 6 due to overloading. Local authorities have had to move all rubbish to the Nam Son Landfill in Soc Son District which is also reaching full capacity.

Xuan Son Landfill has closed due to overloading


The city is facing a rubbish treatment crisis.

In an urgent report announced by the managers of the Xuan Son Landfill, all three tailings ponds built to contain wastewater from buried rubbish at the landfill have already reached their capacity. The ponds now contain about 54,000 cubic metres of wastewater while some 3,000 cubic metres more are kept in temporary containers.

“We’ve been trying to collect the wastewater spill from the overloaded tailings ponds,” the report said. “The problems have been temporarily curbed and we have started a 10-day pilot plan to receive 500 tonnes of waste a day from October 20.”

The managers have also proposed to build more tailings ponds on a 5.6-hectare area in Ba Vi District.

Over the past two weeks, authorities in Son Tay Town have had to gather rubbish in temporary areas while the Xuan Son Landfill closed. Families in some areas have been asked to keep rubbish in their homes as there were no public places to put the waste.

At present, the capital has two landfills, Xuan Son and Nam Son, which are all treating waste by burying. Both of these landfills have constantly operated beyond their capacity and are now already overloaded.

The Xuan Son Landfill used to deal with 1,400 tonnes of rubbish a day which was 230 tonnes higher than their capacity.

In an effort to deal with the problem, Hanoi People’s Committee Vice-Chairman Nguyen Trong Dong has asked the construction department to build a new 2.2-hectare dumping site in Ba Vi District.

Meanwhile, the Soc Son Waste-to-Energy project in Nam Son Waste Treatment Complex which was expected to deal with 90 percent of waste at the Nam Son Landfill failed to finish construction as expected in September.

The project was approved in late 2017 with a total investment of VND7 trillion (USD303 million). Once completed, it will be the largest in Vietnam and the second largest in the world with a capacity of handling 4,000 tonnes of dry solid waste per day.

Speaking with the Tien Phong Newspaper, a representative from the project investor, the Hanoi-based Thien Y Environmental Energy JSC, said that they faced difficulties in employing staff due to the recent Covid-19 outbreak.

Vice-Chairman Nguyen Trong Dong urged the investor to try to put the plant into operation by March next year.

QUẢNG NGÃI — Local ranger and police forces have been tracking illegal hunters who killed five grey-shanked douc langurs (pygathrix cinerea). The remains of the critically endangered species were found at Kon Căng forest in Kon Dốc commune of the central province’s Ba Tơ District.

The grey-shanked douc langur is listed on the International Union for Conservation of Nature red list as one of the world’s 25 most critically endangered primates. The primates can only be found in Việt Nam.

Head of Ba Tơ forest protection section, Ngô Vĩnh Phong, said remains of the five endangered primates were found by a patrol on October 8. The local rangers, police and militia recovered valuable evidence left behind by the hunters which they hope will aid their investigation. 

He said hunters had left the forest when rangers came, leaving the five corpses, one motorbike, an air tank, 53 dust shots and a silencer at the site.

Phong said the illegal hunters used handmade air guns to kill the primates, based on an examination of the bodies.  

The forest is under the management of Ba Tơ forestry private company, he added.

It’s the worst illegal hunting case of endangered wildlife in the province since the start of the COVID-19 pandemic.

According to Frankfurt Zoological Society, some 1,000 grey-shanked doucs have been found in forests of Quảng Nam, Quảng Ngãi, Bình Định, Kon Tum and Gia Lai.

According to the provincial forest department, at least three illegal logging cases have been found in protected forest areas in Phổ Phong Commune of Đức Phổ Town, Sơn Long Commune of Sơn Tây District and Long Môn Village in Minh Long District between late September and early October.

The province plans to allocate 6ha of coastal forest protection area for the development of the Dung Quất-Sa Huỳnh Road. —
