Inside Alibaba Cloud’s Massive Singles’ Day Outage: What Went Wrong?

Note: The image claiming that Ma Huateng said Tencent Cloud is stronger than Alibaba Cloud is likely AI‑generated and false.

Alibaba Cloud Crashed After Singles’ Day

As many know, Alibaba Cloud went down on the day after the Singles’ Day shopping festival.

On the night of Singles’ Day, Taobao experienced a brief outage, but it recovered quickly. However, on the evening of November 12, multiple Alibaba‑related apps—including Taobao, Xianyu, DingTalk, Alibaba Cloud Drive, Ele.me, Tmall Genie, Cainiao, Quark, and Yuque—became inaccessible or showed service anomalies.

Additionally, platforms supported by Alibaba Cloud such as Nasi Cloud charging stations and LeShuang Cooleasy issued urgent notices. The former reported an IoT service API failure that prevented devices from functioning; the latter claimed a nationwide network collapse that affected all platforms.

Alibaba Cloud officially announced at 18:00 that “since 17:44 Beijing time on November 12, 2023, monitoring detected abnormal access to the cloud product console and API calls; engineers are urgently investigating.”

According to Alibaba Cloud’s status page, the issue was not limited to a single availability zone but appeared to be a global‑scale failure, affecting almost every region. Both internal Alibaba services and external offerings such as Financial Cloud and Government Cloud were impacted, with no service remaining operational.

Industry insiders expressed shock, noting they had never witnessed a cloud‑computing failure of this magnitude. Users felt helpless, as self‑help was impossible and they could only wait for Alibaba to restore services.

Given Alibaba Cloud’s massive market share, the impact was extensive. At the recent Cloud Yun conference, Alibaba Group chairman Joseph Tsai highlighted that 80 % of Chinese tech companies and half of large‑model AI firms run on Alibaba Cloud, amplifying the outage’s reach.

Many university students could not use dormitory washing machines because the shared‑laundry service provider relied on Alibaba Cloud. Others faced issues with water dispensers and electric‑bike charging stations.

By 23:59 on the same day, Alibaba announced that core apps such as Taobao, DingTalk, and Alibaba Cloud Drive had largely recovered, and other services were gradually returning to normal.

Did Ma Huateng Praise Tencent Cloud?

On the evening of November 12, a screenshot circulated online claiming a chat record where a user, posing as “Pony Ma Huateng,” shouted, “Using Alibaba Cloud is worse than using Tencent Cloud, friends!” Tencent Cloud later clarified that the screenshot was fabricated.

The incident reignited discussions about “leaving the cloud” or switching providers. While Alibaba’s data‑center scale is enormous and rare worldwide, the question remains whether other cloud vendors could sustain comparable workloads.
