So, the whole conversation I had on #centos-devel was more about link
to their medias than the tree itself, but let me try to summarise
everything there:

I've contacted #centos-devel because the EOL medias are always removed
from vault, in a way that the links would automatically redirect to 
http://vault.centos.org/notonvault.html ... This is expected as a
CentOS release becomes unsupported shortly after a new release comes
out.

The trees follow pretty much the same process as the one followed by
the ISOs. So, for instance, while we have a valid tree for 6.10 (
http://mirror.centos.org/centos/6.10/os/x86_64), the tree for 6.9 is
not valid anymore. Trying to access 
http://mirror.centos.org/centos/6.9/os/x86_64/ you'd get a 404 and 
http://mirror.centos.org/centos/6.9/ has one single file mentioning
that the system has reached its EOL: 
http://mirror.centos.org/centos/6.9/readme

Apart from that, I've also faced some issues where we'd have the tree
but only with the sources but not with the packages. When I asked about
that, the aswer that I got was that apps should not be relying on
vault.

One thing that we can do is to:
- Always add the URL for the current supported release;
- Remove the URL as soon as the new release is done;

What do you think?
