Dynamic Route for CDN (DCDN) provides several types of resource plans that can be used to offset certain resource fees. However, some resource fees cannot be offset by resource plans. This topic describes why you are still charged for resources after you purchase resource plans and how to solve this issue.

Possible causes and solutions

After you purchase resource plans, you may still be charged for resources due to the following causes.

  • Possible cause 1: Some billable items are not included in the resource plans

    Billable items of DCDN are classified into basic services and value-added services. After DCDN is activated, you may be charged for multiple billable items such as data transfer and requests. Each type of resource plan can offset only the specified type of resource fee. For example, outbound data transfer plans cannot offset fees of HTTP requests for static content. In this case, payments or overdue payments are generated.

    Note For more information about billable items, see Overview.


    Check your bills and confirm whether the billable items are included in the resource plans that you have purchased. If a billable item is not included in the resource plans, payments are generated.

    You can check whether value-added services are enabled, such as HTTPS requests for static content and real-time log delivery. Value-added services can be billed on a pay-as-you-go basis. Your account balance pays the payable amount due. You can also purchase resource plans for value-added services. For more information, see Pricing of value-added services.

  • Possible cause 2: The accelerated region of the resource plan is different from the one where fees are incurred

    You must specify an accelerated region when you purchase a resource plan. The resource plan can offset resource fees only in the specified accelerated region. If you purchase an outbound data transfer plan for the Chinese mainland region, this resource plan can offset only outbound data transfer fees that are generated in the Chinese mainland. It cannot offset outbound data transfer fees in Hong Kong (China), Macao (China), Taiwan (China), or other regions outside the Chinese mainland.


    If multiple accelerated regions are set for your accelerated domain names, we recommend that you purchase resource plans for each of the accelerated regions so that resource fees in these accelerated regions can be offset. For more information, see CDN/DCDN Resource Plan.

  • Possible cause 3: The metering method of DCDN is not suitable for the resource plans that you have purchased

    Outbound data transfer plans support only the pay-by-data-transfer metering method. If the metering method of DCDN is pay-by-bandwidth or pay-by-95th-percentile, outbound data transfer plans cannot be used to offset outbound data transfer fees. In this case, payments or overdue payments are generated.


    Change the metering method in the DCDN console. For more information, see Change the metering method.

  • Possible cause 4: The amount of consumed resources has exceeded the quota of the resource plan

    After you purchase a resource plan, the amount of resources that exceeds the quota of the plan is automatically billed on a pay-as-you-go basis. For example, Alice purchased an outbound data transfer plan of 100 GB and the amount of outbound data transfer in the month is 110 GB. The amount (10 GB) that exceeds the plan is billed based on the pay-as-you-go billing method. In this case, an overdue payment may occur.


    • Purchase more resource plans: You can purchase more resource plans to offset resource fees in case more payments or overdue payments are generated. However, resource plans cannot offset fees of resources that are consumed before the resource plans are purchased.
    Note For more information, see Query the details of resource plans.
  • Possible cause 5: Bills are delayed

    A resource plan takes effect immediately after you complete the payment. However, it takes 3 to 4 hours for DCDN to issue a bill after a billing cycle ends. For example, the bill that was issued at 10:00:00 (UTC+8) on October 10, 2020 belongs to the billing cycle from 06:00:00 (UTC+8) on October 10, 2020 to 07:00:00 (UTC+8) on October 10, 2020.


    After you receive a bill, check the time when the bill is issued and the billing cycle of the bill.
