This feels like a Resume Generating Event for the DBA team. Sounds like their DR plan doesn't work or doesn't exist. Even if the devs drew up a breaking schema change that wasn't adequately tested and can't be rolled back, the shot-caller would have moved them into disaster recovery mode a long time ago.
That's assuming they had proper DBAs. Modern ORMs, Docker, and other "DevOps" tools allow you to build stuff without really knowing whats going on.
Edit. An example that comes to mind that you can deploy a mysql cluster in docker with persistent storage. Playing with fire.
