Hello, I have a good news and a bad news.
Good news. The maintainers of mirrors.sjtug.sjtu.edu.cn (an academic free software mirror site) agreed to accept Guix into their support list. Bad news. Their first implementation of a Guix mirror failed. Their server architecture is like this: A front-end program accepts HTTP requests. It looks up the requested resource from a storage server similar to Amazon S3. If the resource is found on storage server, return an HTTP 302 redirection to the storage server. If the resource is not found, return an HTTP 302 redirection to ci.guix.gnu.org and fetch the resource from ci.guix.gnu.org then store it in the storage server. So the next time the same resource is requested, it can be served from the storage server. During the test, we found that guix client does not accept HTTP 302 redirection. So we are working on a different implementation. In the meantime, I think the problem should be reported here and let's find out if something can be done from the Guix side. -- Peng Mei Yu
