Hi Guix, This change is complete and verified. Substitutes are now being successfully served via ci.guix.info, over both HTTP and HTTPS like before. You can also continue to access Cuirass via the same website. Note that due to DNS propagation delay, it may take a few hours before you start seeing ci.guix.info resolve to the new CloudFront name (which is d3j65v8i7zliij.cloudfront.net). If you are curious to see how this has all been set up, please feel free to peruse the contents of the "cdn" directory in the maintenance.git Git repository here: https://savannah.gnu.org/git/?group=guix Happy hacking! -- Chris
