GitLab CI/CD is a DevOps lifecycle tool integrated into GitLab that provides version control, pipelines, release management, security scanning, and artifact handling. Developers configure jobs via .gitlab-ci.yml and can use shared runners or self‑hosted agents.

GitLab.com itself is reachable, but pipelines can stall due to slow package repositories or Docker Hub image pulls from China. Self‑hosted GitLab instances are widely used in China to ensure performance and compliance. GitLab runners inside China often use local mirrors for code and dependency caching. Despite latency, GitLab CI is viable with hybrid setup: self‑hosted for China, gitlab.com for global builds.

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.
