HTTPS Access
While we would like to provide HTTPS access for all hostnames pointing to this mirror, Debian prefers having primary mirrors to not have HTTPS for their ftp.*.debian.org hostname.
If you prefer to access this Debian mirror via HTTPS, please replace https://ftp.ch.debian.org/ by https://debian.ethz.ch/ in your sources.list file.

Inoffical Security Mirror
| Reachable as | security.debian.ethz.ch | HTTP | HTTPS | FTP |
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Its updates are not triggered by a push, hence the mirror may be out of date.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 (you can also use HTTP instead of HTTPS if you want):
Debian 12 "Bookworm" or newer
deb https://security.debian.ethz.ch/debian-security bookworm-security main contrib non-free non-free-firmware deb http://security.debian.org/ stable-security main contrib non-free non-free-firmware
Debian 11 "Bullseye" or newer
deb https://security.debian.ethz.ch/ stable-security main contrib non-free deb http://security.debian.org/ stable-security main contrib non-free
Debian 10 "Buster" or older
deb https://security.debian.ethz.ch/ buster/updates main contrib non-free deb http://security.debian.org/ buster/updates 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.
Use at your own risk!
