Our CDN solution recently changed and I think this was an unintended casualty. The devops team will look at what is needed to get this back up, but it will be a few days I think.
Recently we had an infrastructure change to help us scale content delivery so, as of today, download., cdn. and cdn-alt.* are all pointing to the same backend that does not support rsync.
The work on re-structuring the backend haven’t finish yet. Once we have more news about this, we will let you know.
The infrastructure change mentioned above was how we host the content behind the CDN. We moved to a Cloud Native object store solution to allow for growth, scalability and resiliency that will last well into the future. Unfortunately - this did take away our ability to set up an rsync mirroring service.
My suggestion at this point is to build a script with some logic that checks for newly released builds periodically - using https://download.clearlinux.org/update/version/latest_version. This file points to the latest build value released (in the latest format). With a detected change in that file’s value, you can download a build tree using wget recursively.
