This topic describes the reasons for service suspension and low balance alerts for CDN and DCDN.
Service suspension due to overdue payments
If your instance has an overdue payment, your service is at risk of suspension. The system sends you a notification. To avoid service disruption, renew your service promptly.
Overdue payment notification
If you have an outstanding bill for the CDN service, your account is considered overdue. The system sends you a payment reminder by internal message and email.
Service suspension
If you settle the bill within 15 days after the payment becomes overdue, your CDN service is not affected. If you do not settle the bill within 15 days, the CDN service is suspended.
After your service is suspended due to an overdue payment, CDN immediately stops the acceleration service. Your accelerated domain names are taken offline, and their corresponding CNAMEs are resolved to the invalid address
offline.***.com. As a result, the accelerated domain names become inaccessible.NoteFor more information about taking domain names offline, see Announcement on the adjustment of rules for taking domain names offline (Offline).
After an overdue payment triggers the suspension of your CDN service, the cached resources for the CDN domain names under your account are released from the nodes. The configuration information for the CDN domain names is retained for a maximum of 30 days.
Settle overdue payments and resume service
You can view overdue payment information in the User Center and add funds to your account to settle the payment. After the overdue payment is settled, the CDN service is resumed. Domain names that were taken offline due to the overdue payment are automatically brought back online, and the acceleration service is restored.
If the CDN domain name configurations under your account have been deleted by the system, you must re-add the required domain name configurations after you settle the overdue payment. The CDN nodes also need to re-download and cache resources from the origin server.
Low balance alerts
You will receive a low balance alert for your CDN service in the following situations:
For the pay-by-data-transfer billing method, the system determines whether your account balance is sufficient to cover the fees for the next three billing cycles of the CDN service. This is determined based on the average billable amount of the CDN service over the last 7 hours. If your balance is insufficient, the system notifies you by internal message and email.
For the pay-by-peak-bandwidth billing method, the system determines whether your account balance is sufficient to cover the fees for the next billing cycle (day) for the CDN service based on the billable amount from the most recent billing cycle (day). If your balance is insufficient, the system notifies you by internal message and email.
