(Yicai) Nov. 13 -- Taobao, DingTalk, Alibaba Cloud Disk, and other apps owned by Alibaba Group Holding have been fully restored after being inaccessible or not working properly for more than an hour because of a problem at the Chinese e-commerce giant's cloud computing arm.

Alibaba Cloud's regional consoles in Hangzhou and Beijing have been restored after emergency work, and the services of other regional consoles are gradually being repaired as of 6.54 p.m. yesterday, according to the official group of Alibaba's customer service support on DingTalk. Most regional console services resumed access at 7.20 p.m. after engineers restarted the component services in batches.

Alibaba Cloud began experiencing prblems in cloud product console access and application programming interface calls starting at 5.44 p.m. yesterday, and engineers were urgently investigating, client service support group administrators said on the same day. 

Some 80 percent of China's tech firms and half of the companies developing large language models use Alibaba Cloud, Joseph Tsai, chairman of Alibaba, said at the Yunqi Conference held in Hangzhou from Oct. 31 to Nov. 2.

Previously, Alibaba's Taobao, Tmall, Xianyu, 1688, Fliggy, and other apps collectively experienced login anomalies in March 2019, when Alibaba Cloud suffered a large-scale outage. The issue also affected some internet companies using its services.

Alibaba Cloud has undergone major organizational changes this year. Zhang Yong, former chairman of Alibaba, stepped in as chairman and chief executive of Alibaba Cloud, while as Alibaba's senior management completed a handover in September, new CEO Wu Yongming also took over as Alibaba Cloud's chief executive.
