Burst Bandwidth Alert

You can enable this function and set a bandwidth threshold. When the bandwidth of client requests reaches the threshold, CDN alerts you, helping you identify attacks promptly and prevent excess billing caused by bandwidth theft or attacks.

Scenarios

This function is suitable for domain names with stable bandwidth.

Assume that your domain name example.com consumes 500 Mbit/s to 2 Gbit/s per day and rarely uses over 2 Gbit/s. You can set the bandwidth threshold to 2 Gbit/s. When the bandwidth reaches 2 Gbit/s, alerts are sent to the mobile number and email address bound to your account. You can quickly check the domain access status to prevent high bandwidth caused by attacks and excess billing.
