Develop Informative Out-of-Service Notification Message

We require a clear, concise, and customer-friendly message to inform users when our services are temporarily unavailable or when our company is busy. The message should effectively communicate the current status and provide an estimated time for when services will resume or when they can expect a response. The goal is to manage customer expectations and maintain a positive user experience even during periods of unavailability. The message should be adaptable for various scenarios, such as high traffic, maintenance, or temporary closures.
