Some Packages in rhel-7-server-openstack-8-director-rpms not found

Hello,

i am quite new to all this redhat environment and i hope thats the right place to post something like this.

Background:
I am evaluating Openstack in our company and already installed openstack many times in the last few weeks.
I am also able to download all the other packages everytime without any errors.

Issue:
Now, after the weekend, the installation of the python-tripleoclient package won't succeed because of two packages which belongs to the rhel-7-server-openstack-director-rpms repository.

Those packages are:
openstack-tripleo-heat-templates-0.8.14-11.el7ost.noarch
openstack-tripleo-heat-templates-kilo-0.8.14-11.el7ost.noarch

The error i am getting is just a simple 404 Not found followed by some classy "[Errno 256] No more mirrors to try".

Now my question: Is there a known issue about CDN stuff right now and can i download those packages somewhere else and install them manually?

Thanks in advice,
Tim
