Alibaba Cloud may stop providing technical support for services for a variety of reasons, such as end of service lifecycle, end of third-party support, or evolution of open source projects. We recommend that you stay up-to-date on technical support plans so that you can make informed and timely decisions on whether to update your services or software to general availability (GA) versions. When you use Elastic Compute Service (ECS), pay attention to the lifecycle plans of the operating systems contained in images that you used to create ECS instances. You can visit the official websites of the operating systems to obtain information about their lifecycle plans.

Note When an operating system version reaches its end of life (EOL), Alibaba Cloud stops providing support for ECS instances that run the operating system version.
  • Alibaba Cloud Linux 2 is an operating system provided by Alibaba Cloud. Alibaba Cloud provides technical support for issues that you encounter when you use Alibaba Cloud Linux 2 up until the operating system reaches its EOL.
  • If you are using a third-party operating system, contact the operating system vendor or the open source community for technical support. Alibaba Cloud also provides information about image- and system-related issues. If a third-party vendor stops supporting or maintaining its operating system, Alibaba Cloud also stops providing corresponding technical assistance.
