Sid (unstable) installer?

[Stefan Salewski <Salewski@physnet.uni-hamburg.de>]

Hello,

I have some trouble finding the Sid installer.

https://alioth.debian.org/docman/view.php/30192/21/debian-amd64-howto.html#id230754 

points me to

Sid:http://cdimage.debian.org/pub/cdimage-testing/sid_d-i/amd64/current/.

There I find

debian-testing-amd64-netinst.iso

I burnd this image to CD, booting it gives me the message
"This is Debian etch installation CD, ..."

But I want to install Sid=Unstable!

What is wrong?
