In a well-managed engineering organization, it shouldn't be stressful. Sense of urgency, sure, but stress is typically only making things worse.

stressing out and panicing is the worst thing you can do in this situation.

usually, keep your head cool and focus on the problem at hand.

This is also the reason why engineering/operations should be seperate from customer communications. The people who are fixing the issue should not also be the ones doing the communication with the outside world.
