This sort of crisis management is always a challenge. How do you communicate this sort of problem to customers without losing credibility later if there is a risk of lingering issues? Based on the tone of the email that you posted, as a customer, I would expect the problem solved, case closed. Certainly, it makes customers feel good that the team has it handled.

The new events, if not handled quickly, could create doubt in customer minds and the team, as the optimistic outlook may not hold. I hope they beat this soon.
