Public bug reported: When requesting byte ranges near the end of the .ddeb file (for example Range: bytes=209715200-210763775), the server responds with HTTP/1.0 504 Gateway Time-out. Earlier ranges (e.g. bytes=1000-686719) are served with HTTP/1.1 206 Partial Content and a cache response header. This behavior indicates that the CDN/cache holds the file head but not the requested high-offset segments; the edge attempts to fetch those segments from the origin and the origin request is timing out. Please check origin access times and proxy/back-end timeout settings for partial-range requests.
