An Alibaba Cloud outage on November 12, 2023 caused yellow alerts, console and API failures, and service disruptions for Alibaba products such as Taobao, Xianyu, DingTalk, and Yuque, traced to an OSS storage component failure and detailed with a timeline, cause analysis, and personal reflections.
Hello, I'm Louzi.

02 Event Timeline
18:16 Alibaba Cloud official response:
"The text is too small, posting the original."
Dear customer,
At 17:44 Beijing time on 2023‑11‑12, Alibaba Cloud monitoring detected abnormal console access and API calls. Engineers are urgently investigating. We apologize for the inconvenience.
Progress updates:
17:50 Alibaba Cloud confirmed the fault is related to an underlying service component; engineers are handling it urgently.
18:54 After engineer intervention, consoles in Hangzhou, Beijing and other regions recovered; other regions are gradually restoring.
19:20 Engineers performed batch restarts of component services; most regional consoles have resumed access.
03 Root Cause
The outage originated from Alibaba Cloud's Object Storage Service (OSS), a storage component.
OSS is an object storage service that separates large data files into metadata and object data for storage.
For Alibaba Cloud, OSS is a component with reliability up to 99.975%.
Stability is a key annual metric; the prolonged outage likely dropped availability below three nines.
04 Reflections
The incident had a huge impact; based on my experience in large tech firms, not receiving a year‑end bonus is a relatively mild penalty.
Engineers should not treat this as entertainment; the team involved will feel intense pressure, scrutiny, and the need for thorough post‑mortems.
Hope you can endure the pressure and get through it.
Finally, respect online systems and stay away from accidents.
My motto: I walk from dawn to embrace the night stars; there are no shortcuts, we are all ordinary, hello stranger, let’s encourage each other.
