Billing

WSA is billed for the basic fee and value-added service fee. For details, see Table 1. For details about pricing, see Product Pricing Details.
After WSA is enabled, you will be billed by WSA for WSA domain names. CDN and WSA resource packages cannot be used to deduct traffic charged by the other service.

**Table 1** WSA billing
Billing Item	Billed By	Description
Basic service fee	Traffic	You are billed by the traffic used per hour. You can also buy traffic packages to deduct traffic used.
	Peak bandwidth	The system measures and records a peak bandwidth every 5 minutes, so 288 records are collected per day. The highest peak bandwidth per day is used as the billable bandwidth.
	95th percentile bandwidth	In each calendar month, the peak bandwidth is measured and recorded on each valid day. At the end of the month, the records are sorted from the highest to the lowest, and the top 5% of the records are thrown away. Then the highest bandwidth value in the remaining records is the billable bandwidth of the month and a bill is generated based on the contract price.
	Average daily peak bandwidth	At the end of each calendar month, the system calculates the average of peak bandwidth of valid days in this month. The average value is the billable bandwidth of the month and a bill is generated based on the contract price.
Value-added service fee	Whole site acceleration request	You are billed by the number of whole site acceleration requests for dynamic and static content.
