Your question is Owning a Failed Production Deployment. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
Tell me about a time you had to troubleshoot a failed deployment. Walk me through how you diagnosed the issue, how you communicated during the incident, and what you did afterward to prevent it from happening again.
