Yesterday when I ran the staging playbook it took down the servers because it upgraded ruby, but did not add bundler into the gems for the new ruby. I had to manually upgrade the ruby on one machine and had to add the bundler gem manually on both servers.
Try running the playbook on both pdc-discovery-prod machine individually to make sure they will work in the future.
