The links below the part "Release Archive" are still direct to the openwrt.org, however the files are all be storaged in the mirror site. So maybe there might be some mistake?
@paulzhn, welcome to the communty!
- Can you show us what you're talking about?
- What mirror?
- What version?
The urls below the part Release Archive on index page for every mirror always direct to the downloads.openwrt.org. However those files are also existed in the mirror. For example, the France mirror https://openwrt.tetaneutral.net/.
It seems like the problem exists in every mirror using rsync.
