CentOS 8 EOL and OBS

Hi, with CentOS 8 being EOL, and the binary repositories now gone: * will building packages for CentOS 8 keep working in the public OBS? * will building packages for CentOS 8 keep working in private instances for OBS? Right now, both are still working. I guess this is because of cached packages, that will expire at some point and then it starts failing? Or is the public OBS possibly building all of the CentOS packages and that gets used instead of the official repositories, and it will keep on working for some years? If that assumption is true, is that also where the private OBS instances download packages from? Thanks! Best, Oliver
