Travis CI is a hosted continuous integration service for GitHub and Bitbucket projects. It runs builds on Linux, macOS, and Windows environments, supports matrix builds, caching, and deployment to cloud services. Configuration is declared in .travis.yml files within each repository.

Travis CI’s build orchestration endpoints and status badges are inaccessible in mainland China without circumvention tools. Builds triggered by Chinese-hosted repositories may fail to report status. Chinese teams often migrate to domestic CI/CD platforms (e.g., Tencent TStack CI, Alibaba Cloud DevOps) or self-host open-source alternatives like Jenkins and GitLab CI.

The information regarding service availability in China is provided for general reference purposes only. Due to the dynamic nature of network conditions and regulatory environments, the actual accessibility of these services may vary over time and by location. Users are advised to verify the current status independently.
