Please go to the openSUSE Build Service (OBS) download location at
http://download.opensuse.org/repositories/Kernel:/ if you are looking
for the Kernel of the Day for x86_64. This site is only needed when
testing SLE kernels on non-x86 architectures. Starting with SLE12, we can
even build POWER and s390x packages in the OBS.

Ask in the public mailing list <opensuse-kernel@opensuse.org> if you
have any questions.
