Hi, I've reconfigured our apt-cacher to use HTTPS for communications with deb.debian.org since that is known to work well. So, all use of deb.debian.org through our apt-cacher will use HTTPS between BitFolk and deb.debian.org. You don't need to (and can't) change anything on your end. If you know of other in-use mirror sites that are reliable on HTTPS then I'm happy to switch them over too. Reply here or send a support ticket please.
