Cross-posting from the ROS status site: https://status.ros.org/incidents/r1l8hs9vfbzw
We’re changing the volume type of the build farm repository host which requires the host to be offline for a disk snapshot and copy. We’ll use the downtime to perform updates and reboot build.ros.org as well since the build farm can’t run while the rosdistro caches are unavailable.
The primary ROS repositories at http://packages.ros.org will remain available.
This will begin after the Kinetic sync.
