    • Anycast Internet Acceleration (AIA) is currently in beta. To try it out, please apply to be a beta user.
    • AIA is now available in the following regions: the Chinese mainland, Hong Kong (China), Japan, South Korea, Thailand, Singapore, India, United States, Russia, and Frankfurt.


    AIA fees consist of two parts: public network fee and IP resource occupation fee.


    In this document, the Asia Pacific region covers Hong Kong (China), Japan, South Korea, Thailand, Singapore, and India. The North America region covers the United States. The Europe region covers Russia and Frankfurt.

    Public network fee

    The public network fee of AIA is billed by bandwidth at a unit price higher than that of the public network. Specifically, you will be charged by monthly 95th percentile of either the outbound or inbound bandwidth (whichever is higher) in USD/Mbps/month as shown below:

    Server RegionPublic Ingress/Egress Region
    Chinese mainland Asia Pacific North America Europe
    Chinese mainland 18.86 - - -
    Asia Pacific - 18.86 18.86 18.86
    North America - 18.86 18.86 18.86
    Europe - 18.86 18.86 18.86


    95th percentile: fees are billed by calendar month. In a calendar month, all the valid 5-minute bandwidth values are sorted in descending order, and the top 5% are removed. The highest value of the remaining values is used as the 95th percentile of the monthly peak bandwidth.
    Assume that all the bandwidth value points in a month of 30 days are valid. Because one value point is generated every 5 minutes, 12 value points are generated every hour, and 8,640 (12 x 24 x 30 = 8,640) value points are generated every month. All the value points are sorted in descending order, the top 5% (8,640 × 5% = 432) are removed, and the bandwidth value of the 433rd point will be billed.

    Anycast EIP resource occupation fees

    An Anycast EIP that is not bound to instances will incur a resource occupation fee. For more information, please see the “IP Resource Fee” section in Elastic IP Billing.

    Billing Examples

    Suppose you purchased multiple Anycast EIPs under an account. The public network traffic generated by these Anycast EIPs in a month will be aggregated, and billed by 95th percentile of the monthly bandwidth at a price as shown below:

    Server Region Public Ingress/Egress Region Bandwidth Usage (Mbps) Price (USD/Mbps/Month)
    Asia Pacific North America 10 18.86
    Asia Pacific Chinese mainland 100 29.33
    Europe North America 200 18.86
    Asia Pacific Asia Pacific 300 18.86

    Final fees = 10 * 18.86 + 100 * 29.33 + 200 * 18.86 + 300 * 18.86 = 12,551.60 USD
