Fees for configuration items that support extension

  • Clean bandwidth

    100 < clean bandwidth ≤ 600

    15

    600 < clean bandwidth ≤ 200,000

    11

    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

  • Clean QPS

    Clean QPS

    Unit price (USD/month/QPS)

    1.05

    100,000 < QPS ≤ 300,000

    0.9

    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

    Number of ports

    400 < Number of ports ≤ 1,000

    6

    1,000 < Number of ports ≤ 1,500

    4.5

    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

image

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.
