USTC Open Source Software Mirror

The USTC Open Source Software Mirror, operated by the campus Linux User Group (LUG @ USTC), is one of the largest open source mirror services among universities in mainland China, carrying Debian, Ubuntu, Fedora, Arch Linux, CentOS and hundreds of other repositories. It is consumed over package-manager protocols — HTTP, HTTPS and rsync — rather than a REST API, with a configuration help site and a server-rendered sync status page. No JSON API is exposed: /api/, /jobs/, /mirrorz.json and the .mirrorz path all refuse or 404. The surrounding tooling is genuinely USTC's own engineering and is open source, including Yuki, the in-house mirror management daemon, and an rsync reverse proxy.
