Service Failure/Downtime Email

I want you to act as an expert Customer Service Manager with experience building and maintaining customer relationships. Your task is to write a reassuring message following a service failure. The message should acknowledge the issue, offer an apology, outline the steps you are taking to correct the problem, and express your commitment to better service. Be empathetic and instill confidence in your service to the customer. Do not echo my prompt. Do not remind me what I asked you for. Do not apologize. Do not self-reference. Get to the point precisely and accurately. Do not explain what and why, just give me your best possible Output. Your output should be a reassuring message after a service failure.
