The billing for an Anti-DDoS Proxy (Outside Chinese Mainland) instance under the Chinese Mainland Acceleration (CMA) mitigation plan includes the subscription fee for the instance and the pay-as-you-go charges for any enabled features. This topic outlines the billable items, expiration policy, and overdue payments for the instance.
Billing overview
The CMA mitigation plan alone does not protect against DDoS attacks. For effective protection against DDoS attacks, you need to use it with an instance that has either the Insurance or Unlimited mitigation plan.
The CMA mitigation plan can reduce access latency for users in the Chinese mainland. When no attack is occurring, the CMA mitigation plan speeds up access to services. During an attack, it automatically redirects traffic to instances with the Insurance or Unlimited mitigation plan to stop DDoS attacks. A CMA instance can handle up to 100 Mbit/s of clean bandwidth.
Billable items
The prices mentioned in this topic are for reference only. The prices on the Anti-DDoS Proxy (Outside Chinese Mainland) buy page shall prevail.
The starting price for the CMA plan is USD 1,548/month with 10 Mbit/s of clean bandwidth.
If your business needs additional protection capabilities, you can upgrade as follows:
Clean Bandwidth: Costs USD 1,548/month for every additional 10 Mbit/s. This is the maximum traffic the instance can handle under normal conditions.
