A couple of days ago, our moodlehq/moodle-db-oracle docker-hub repository disappeared:
Worse yet, any attempt to recreate it, from github, from docker-hub UI, pushing a local image ends with “Repository with this Name and Namespace already exists” message.
So, we are locked, right now. And CIs are already starting to fail whenever they try to pull the non-existent repo.
I've asked about the problem @ Docker forums, let's see if there is any answer/solution there or we'll need to consider changing to another (non-locked) repo name.
Update: Andrew Nicols found this, commented there too: https://github.com/docker/hub-feedback/issues/1741
