This topic describes why the Dynamic Route for CDN (DCDN) service is suspended and how to enable low balance alerts.

Service suspension

Note If you have an overdue payment, the system sends you a notification. In this case, we recommend that you settle your overdue payment at the earliest opportunity to prevent service suspension.
  • Overdue payment alerts

    When a payment becomes overdue, the system notifies you by text messages or emails.

  • Service suspension
    • If you settle the payment within 15 days after the payment becomes overdue, DCDN is not suspended. If you do not settle the payment within 15 days after the payment becomes overdue, DCDN is suspended.
    • The service suspension rules vary based on the time when the payment becomes overdue, as described in the following table.
      Before 00:00:00 (UTC+8) on April 11, 2022 After 00:00:00 (UTC+8) on April 11, 2022 (excluding the 30-day grace period)
      Accelerated domain names are disabled. The status of the accelerated domain names changes to Offline. Within the following 30 days, the accelerated domain names are resolved to the origin IP addresses by using their CNAMEs. 30 days after the accelerated domain names are disabled, the accelerated domain names are no longer resolved to the origin IP addresses. The CNAMEs of the accelerated domain names are resolved to the invalid address offline.***.com. As a result, the accelerated domain names become inaccessible. DCDN is immediately suspended, the accelerated domain names are disabled, and the status of the accelerated domain names changes to Offline. The CNAMEs of the accelerated domain names are resolved to the invalid address offline.***.com. As a result, the accelerated domain names become inaccessible.
      Note For more information, see Rules for disabling accelerated domain names.
    • After DCDN is suspended, the resources that are cached on the DCDN nodes are released. The configurations of the accelerated domain names are retained for one month.
  • Payment settlement and service restoration

    You can check your overdue payments in Expenses and top up your account balance to settle the payments. After overdue payments are settled, domain names that are in the Offline state due to overdue payments are automatically enabled. DCDN is automatically restored for the domain names.

Low balance alerts

Low balance alerts are sent to you in the following scenarios:
  • Pay-by-data-transfer: The system determines whether you have a sufficient balance in your Alibaba Cloud account to pay for the next three billing cycles based on the average payable amount of the last 7 hours. If you do not have a sufficient balance in your Alibaba Cloud account, the system notifies you by text messages or emails.
  • Pay-by-bandwidth: The system determines whether you have a sufficient balance in your Alibaba Cloud account to pay for the next billing cycle (day) based on the payable amount of the most recent billing cycle (day). If you do not have a sufficient balance in your Alibaba Cloud account, the system notifies you by text messages or emails.
