Debian Mirror
This is one of the official Debian mirrors and also known as ftp.ch.debian.org. Debian is a community-developed free operating system. Debian GNU/Linux is based on the basic system tools of the GNU project and the Linux kernel. Debian was created in August 1993 by Ian Murdock and has been actively developed ever since. It is one of the oldest, most influential and most widely used GNU/Linux distributions. Many other Linux distributions are based on Debian, of which Ubuntu is the best known.

deb-src https://debian.ethz.ch/debian stable main contrib non-free
Inoffical Security Mirror
Our security mirror is no official security mirror and only thought as local cache. See the debian security FAQ for reasoning.
Its updates are not triggered by a push, hence the mirror may be out of date. If you want to use it, we suggest to use it like this
Sample /etc/apt/sources.list
deb https://security.debian.ethz.ch/debian-security stable-security main contrib non-free
deb https://security.debian.org/debian-security stable-security main contrib non-free
So if this security mirror already has the updated package mirrored, it's fetched from there as it's the first hit for the newest version. If not, the newest package is still already available and fetched from the official servers.
Rsync protocol
The main debian archives are also accessible by rsync.
rsync debian.ethz.ch::debian
rsync debian.ethz.ch::debian-cd
rsync debian.ethz.ch::debian-archive
rsync debian.ethz.ch::debian-debug
