We have issued an update to the yum for CentOS 6.10.  These updated packages are just to fix the following bug:

https://bugs.centos.org/view.php?id=12872

There is no change in functionality for yum, the change is that Error 403, 404, and 60 now point to this wiki page:

https://wiki.centos.org/yum-errors

and no longer point to point to access.redhat.com articles.

The updated RPMS are: yum-3.2.29-81.el6.centos.0.1.noarch.rpm yum-cron-3.2.29-81.el6.centos.0.1.noarch.rpm

SRPM: yum-3.2.29-81.el6.centos.0.1.src.rpm

Thanks, Johnny Hughes
