Steps to reproduce:
1. Install Ubuntu without any changes in /etc/apt/sources.list
(ensure that is has http://security.ubuntu.com/ubuntu

$ grep http://security.ubuntu.com/ubuntu /etc/apt/sources.list | grep -v ^#
deb http://security.ubuntu.com/ubuntu xenial-security main restricted
deb http://security.ubuntu.com/ubuntu xenial-security universe
deb http://security.ubuntu.com/ubuntu xenial-security multiverse
$

).
2. Launch `software-properties-gtk` and select local mirror, for example Switzerland mirror.switch.ch (or *Select Best Server*), *Reload* lists and check again:

$grep http://security.ubuntu.com/ubuntu /etc/apt/sources.list | grep -v ^#
$ # returns nothing

Notes:
* I discovered this while upgrading my machines to fix Meltdown vulnerability (as bug 1741934 and kernels 4.4.0-108 and 4.4.0-109). Only one my machine was upgraded to 109. It used *Main server* and http://security.ubuntu.com/ubuntu.
* All releases seems to be affected by this mirror-problem.

Expected results:
* Ubuntu must save http://security.ubuntu.com/ubuntu mirror in /etc/apt/sources.list for really fast fixing of critical bugs

Actual results:
* Ubuntu switches all mirrors and disables http://security.ubuntu.com/ubuntu .
