The fees of an Anti-DDoS Proxy (Chinese Mainland) instance consist of two parts: the subscription fee for purchasing the instance, and the pay-as-you-go fees that accrue after you enable pay-as-you-go features. This topic describes the billable items, expiration policy, and overdue payment policy of Anti-DDoS Proxy (Chinese Mainland) instances.
Instance types
Anti-DDoS Proxy (Chinese Mainland) is available in two instance editions. You can purchase a Professional Edition instance directly on the buy page. To purchase a Premium Edition instance, contact your account manager before purchase.

Billing
Actual prices are subject to the Anti-DDoS Proxy (Chinese Mainland) buy page.
Total fee = subscription instance fee + pay-as-you-go fees.
Part 1: Subscription instance fees
Subscription instance fee = basic instance fee + fees for each extended configuration item.

Premium Edition
Only a basic protection bandwidth of 5 Gbps is supported. The basic instance fee is USD 2,880/month.
The configuration items covered by the basic instance fee are set to the default minimum specifications listed in the following table. You can extend the specification of a configuration item based on your business needs.
Configuration item | Professional Edition specification values | Premium Edition specification values | Billing method | Description |
Burstable protection bandwidth | 30 Gbps | Not supported | Pay-as-you-go | Pay-as-you-go fees are generated when the protection bandwidth is greater than the basic protection bandwidth and less than the burstable protection bandwidth. |
Clean bandwidth | 100 Mbps | 100 Mbps | Subscription | The maximum service traffic that the instance can handle when no attacks are detected. The specification can be extended. |
95th percentile burstable clean bandwidth | Daily 95th percentile | Daily 95th percentile | Pay-as-you-go | Pay-as-you-go fees are generated when the actual bandwidth is greater than the clean bandwidth and less than the 95th percentile burstable clean bandwidth. |
Clean QPS | 3,000 | 3,000 | Subscription | The maximum concurrent request rate for HTTP and HTTPS services that the instance can handle when no attacks are detected. The specification can be extended. Note Set this parameter based on your actual service usage. If your actual service usage exceeds the Clean QPS specification that you selected at purchase, service requests may be dropped and full logs may be incomplete. |
95th percentile burstable QPS | Daily 95th percentile | Daily 95th percentile | Pay-as-you-go | Pay-as-you-go fees are generated when the actual QPS is greater than the Clean QPS and less than the 95th percentile burstable QPS. |
Function plan | Standard Plan | Standard Plan | Subscription | Includes the Enhanced function plan and the Standard function plan. On top of the Standard function plan, the Enhanced function plan improves the service access capability and the DDoS attack mitigation capability of Anti-DDoS Proxy. For more information, see Differences between the standard and enhanced function plans. |
Number of protected domain names | 50 | 50 | Subscription | The number of HTTP and HTTPS domain names that can be added to the instance. The specification can be extended. Every 10 additional domain names allow one additional top-level domain. For example, when the value is 50, the total number of top-level domains to which all domain names belong cannot exceed 5. |
Number of ports | 50 | 50 | Subscription | The number of TCP and UDP ports that can be added to the instance. The specification can be extended. |

For example, if you select 500 Mbps for the clean bandwidth when you purchase an instance, you pay the following monthly fee for the extended clean bandwidth:
(100 - 0) × 0 + (500 - 100) × 15 = USD 6,000

For example, if you select 6,000 for the Clean QPS when you purchase an instance, you pay the following monthly fee for the extended Clean QPS specification:
(3,000 - 0) × 0 + (5,000 - 3,000) × 1.5 + (6,000 - 5,000) × 1.425 = USD 4,425

For example, if you select the Standard function plan and set the number of domain names to 600 when you purchase an instance, you pay the following monthly fee for the extended number of protected domain names:
(50 - 0) × 0 + (200 - 50) × 4.5 + (600 - 200) × 4.2 = USD 2,355
Number of ports

For example, if you set the number of ports to 200 when you purchase an instance, you pay the following monthly fee for the extended number of protected ports:
(50 - 0) × 0 + (150 - 50) × 7.50 + (200 - 150) × 6.75 = USD 1,087.5
Part 2: Pay-as-you-go fees
You can choose whether to enable each pay-as-you-go feature based on your business needs. After a feature is enabled, a pay-as-you-go bill is generated only when the conditions for incurring fees are met.
Feature | Billing method | Description |
Burstable protection bandwidth | Pay-as-you-go (daily) | Supported only by Professional Edition instances. The burstable protection bandwidth indicates the maximum capability of an Anti-DDoS Proxy instance to mitigate DDoS attacks. Attacks that exceed the basic protection bandwidth are mitigated by burstable protection, and a pay-as-you-go bill is generated. For more information, see Billing of elastic protection capability. |
Burstable clean bandwidth | Pay-as-you-go (daily or monthly) | The burstable clean bandwidth feature elastically increases the clean bandwidth of an instance on top of its clean bandwidth specification. It resolves service throttling caused by normal service traffic fluctuations that exceed the clean bandwidth specification of the instance during peak hours. For more information, see Billing of burstable clean bandwidth. |
Burstable QPS | Pay-as-you-go (daily or monthly) | The burstable QPS feature elastically increases the Clean QPS of an instance on top of its Clean QPS specification. It resolves service throttling caused by normal Clean QPS fluctuations that exceed the Clean QPS specification of the instance during peak hours. For more information, see Billing of burstable QPS. |
Expiration policy
Time period | Service traffic forwarding | Instance configuration |
Within 7 calendar days (exclusive) after expiration | The instance retains a Blackhole filtering threshold of 5 Gbps. Blackhole filtering is triggered when forwarded service traffic and attack traffic exceed 5 Gbps. | The instance configuration is retained. |
From 7 calendar days (inclusive) to 15 calendar days (exclusive) after expiration | Service traffic forwarding is stopped and resumes after renewal. Warning If you no longer use Anti-DDoS Proxy (Chinese Mainland), make sure that you switch service traffic from Anti-DDoS Proxy to your origin server at least 7 calendar days before the instance expires. For website services, make sure that domain name resolution does not point to the CNAME address of Anti-DDoS Proxy. For non-website services, make sure that your service IP address does not use the exclusive IP address of Anti-DDoS Proxy. Otherwise, service access is affected when the instance expires. | The instance configuration is retained. |
The 15th calendar day after expiration | Service traffic forwarding is stopped. | The instance is released. Warning After all Anti-DDoS Proxy instances under your account are released for 30 days, the system automatically clears all associated domain and port forwarding rules. The 30-day countdown starts from the release of the last instance. |
Overdue payments
Your account is considered to have an overdue payment when its available balance, including cash, vouchers, and coupons, cannot settle issued bills.
After your account has an overdue payment, top up your account promptly to keep a sufficient balance and avoid service unavailability.
Renewal policy
Instances support manual renewal and auto-renewal. For instructions, see Renew an instance.
Refund policy
Refunds are not supported after purchase.
Bill query
You can query bills in Expenses and Costs. For more information, see Overview of Monthly Bill.
