Hi Mirrors Admin,

Karanbir and myself had a conversation about CentOS 7 and external mirrors and here are some points we'd like to report:

First, we'd like to say thank you for the CentOS Mirror you actually provide for all CentOS users all around the world.

Second point I wanted to mention is the fact that CentOS 7 is slowly approaching. What does that mean for you ? Don't be surprized if in the following days/week(s), your CentOS mirror will start consuming more disk space and bandwidth. We have currently no fixed disk space usage stats for 7, but we expect it to be ~40Gb (os/updates/iso images) and that will grow with new updates being released when they'll appear. Keep in mind that that will be for i386/x86_64 and we just plan on releasing x86_64 now, i386 being a community effort, and considered secondary arch (so building in parallel but we'll release x86_64 even if there is no i386 build "ready")

To better serve you, we'll start implementing the following changes in the next 24 hours : - we'll restrict the CentOS (and - legacy but pointing to the same path - CentOS-incdvd) rsyncd modules access to IP currently being marked as "official" CentOS public mirrors - That means that we'll currently stop adding new mirrors until Seven is out - That also means that if you're using a different outgoing IP address than the reverse ip lookup for your mirror(s), you'll be blocked (if that's the case, contact us on the centos-mirror list and we'll fix that )

Can we also remind you (http://wiki.centos.org/HowTos/CreatePublicMirrors) that : * if your mirror is located in the .us, you're encouraged to use the us-msync.centos.org::CentOS host/rsync module * if your mirror is located somewhere in Europe, you're encourage to use the eu-msync.centos.org::CentOS host/rsync module * Mirror out of the .us/.eu scope can use the generic msync.centos.org::CentOS host/rsync module (multiple nodes using GeoIP to redirect to the nearby country/host)

We count on you for a successful CentOS 7 release, and would like to thank you once again.

If you have questions, feel free to start a new thread on the centos-mirror list,

Kind Regards,
