Not all servers come with RedHat Linux 9.0
As far as I'm aware a lot of datacenters do still supply 8.0, one of
those being Nocster and actually quite a few others. Lots too
also still supply 7.3 since it is only being unsupported in December
this year, or was it October? Anyhow - it is still in for support and
therefore people still offer it.
