I'm using "static file" to mean something pre-recorded that even if users will view in order, they will likely start at different times, so different users will be viewing different parts of it. In contrast to a live stream where everyone is viewing the same part at the same time, and once that part passes nobody is likely to view the old part ever again. This makes a big difference in terms of network design.
