Hi Guix, Apologize for the name change! I can't resist when I thought of the domain name...

Let > me know if you're interested in hosting one :) Redirection of cache-cdn is now avoided by using Cloudflare Workers to act as the frontend, it's truly behind "CDN" now. In case you dislike Cloudflare, only cache-cdn is behind it, though mirrors may proxy substitutes from Cloudflare R2. I have migrated the head node to a machine with more storage and started building Guix channel, reusing substitutes from official servers. Hopefully it will be an option for those with slow connection to official servers in a few days. I'll keep the build farm running in the long term, so I'm seeking donation on mirror hosting, and financial support to share the expenses (cache-cdn, object storage and mirrors I host. Currently they are for demonstration purpose, I may strip them out if necessary to reduce the expenses). More information is available in the blog post: <https://ultrarare.space/en/posts/guix-build-farm/> Thanks
