欠费后如果在延停权益额度内，您的服务将不会受到停服影响。
NoteAlibaba Cloud provides the extended suspension-free benefit. When a pay-as-you-go resource is overdue, you can continue to use cloud services for a certain amount or duration. Normal fees apply during the extended period. For more information, see Extended Suspension-Free Benefit.
If your account has an overdue payment that exceeds the service suspension protection quota, Alibaba Cloud immediately stops the NAS service. Only the data stored in the NAS file system is retained. No new fees are generated after the service is stopped.
