I have received a few emails and a few patches wrt $subject, so I will respond on this list instead of individually. Last night, sometime around midnight UTC, the entire rdo/images directory was deleted from the CentOS artifacts server. I have asked folks on #centos-devel if this was intentional, and it was not. However, we don't have a root cause for how it happened yet. Luckily, we had the images mirrored to the CDN for liberty and mitaka, and I had a local image for master. I have manually re-uploaded all images to the artifacts server. I will update this thread, when/if there is more details as to the root cause. -trown
