This topic explains the causes of low balance alerts and the suspension of Alibaba Cloud CDN.

Service suspension

Note Alibaba Cloud CDN sends you a notification if you have an overdue payment. You must complete overdue payments at the earliest opportunity to ensure service continuity.
When an overdue payment occurs, the system notifies you by text messages or emails.
  • If you complete the payment within 15 days after it becomes overdue, Alibaba Cloud CDN will not be suspended. If you do not complete the payment within 15 days after the payment becomes overdue, Alibaba Cloud CDN service will be suspended.
  • The status of the domain names accelerated by Alibaba Cloud CDN will change to offline. Within 30 days after accelerated domain names are disabled, the domain names will be directly resolved to the origin servers. After 30 days, the accelerated domain names will no longer be resolved to the origin servers and their CNAMEs are mapped to the invalid domain nameoffline.***.com. In this case, the accelerated domain names are inaccessible. For more information, see Rules for disabling accelerated domain names.
  • After Alibaba Cloud CDN is suspended, the resources cached on CDN edge nodes will be removed. The configuration information about the accelerated domain names will be retained for one month.

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 during 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 during 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.
