Rate limiting

If your domain name is attacked or has malicious traffic coming, there may be sudden traffic spikes that result in a bill higher than your normal expenditures. In this case, you can enable usage cap. Once the consumed bandwidth or traffic reaches the cap in a specified period, CDN acceleration will be disabled for this domain name. You can set unblock duration to automatically enable the acceleration for the domain name. If you choose manually unblock, you will need to enable the acceleration for the domain name on the console.
