Tsinghua University TUNA Open Source Mirror

The TUNA open-source software mirror is the one surface Tsinghua publishes that behaves like a public API. It is operated by TUNA (Tsinghua University TUNA Association), a student association, on the university's own registrable domain and infrastructure, and it serves two unauthenticated JSON documents. /static/tunasync.json reports the synchronization state of every mirrored repository — name, status, upstream source, on-disk size and five timestamps per mirror — and drives the site's public status dashboard. /static/status/isoinfo.json is the catalog behind the installable-images page: 66 entries across three categories (os, font, app), each with a list of named, mirror-relative download paths. Both were verified live on 2026-08-19. The document shapes come from TUNA's own MIT-licensed software (tunasync, mirror-web); no formal specification is published by TUNA, so both OpenAPI descriptions here were written from the live responses. Caller beware: the edge returns 403 with an HTML denial page to browser-shaped User-Agents while returning 200 to plain tool User-Agents.
