In my experience customers deeply detest the idea of waiting around for a failure case to re-occur so that you can understand it better. When your customers are losing millions of dollars in the minutes you're down, mitigation would be the thing, and analysis can wait. All that is needed is enough forensic data so that testing in earnest to reproduce the condition in the lab can begin. Then get the customers back to working order pronto. 20 minutes seems like a lifetime if in fact they were concerned that the degradation could happen again at any time. 20 minutes seems like just enough time to follow a checklist of actions on capturing environmental conditions, gather a huddle to make a decision, document the change, and execute on it. Commendable actually, if that's what happened.
