Hi Mirrors Admins,
As you probably know, CentOS 6.8 is now built. So expect to see some traffic when it will be released - very soon - (when the whole tree/isos will land on your mirror, and when people will then start downloading/rsyncing from your mirror).
Just to let you know also that expected size is ~31Gb. After some time we'll remove the 6.7 folder and will archive it to vault.centos.org, so you'll get back that space.
If you have questions, feel free to discuss that on the centos-mirror list, or in #centos-mirror, on irc.freenode.net
Kind Regards,
