The CentOS Infrastructure team will be moving the machines hosting cbs.centos.org, ci.centos.org and accounts.centos.org on October 10th, 2016. We expect a downtime of 48hrs. Contact us in #centos-devel on freenode at any time during that period for questions, or watch the centos-devel mailing list for the latest updates.
The servers, switches, PDUs, and even the racks themselves hosting CBS, ci.centos.org, accounts.centos.org and registry.centos.org are all stored in a datacenter in Raleigh, North Carolina, USA and will be moved to a new space in the datacenter on Monday October 10th. This new space provides a little bit of expansion room for the future of these services and consolidates networks that were previously separate (namely the CICO cloud with the rest of the CI infrastructure). During this window, all services related to the listed CentOS properties will be down.
We blocked out 2 days (48hrs) to do the move, but we will do our best to restore services as soon as it is possible to do so.
