Changes
Users who purchase Anti-DDoS Service will have the burstable clean bandwidth and burstable QPS billing features enabled by default.
Burstable clean bandwidth and burstable QPS will no longer support the Monthly 95th Percentile billing mode or manual shutdown feature. Only the Daily 95th Percentile billing mode will remain.
The peak burstable clean bandwidth is fixed at 10 times the clean bandwidth and is no longer adjustable. For more information, see Billing description for burstable clean bandwidth.
The burstable peak will be adjusted to serve as a water level alert indicator. The product's burstable billing statement will be generated based on the 95th percentile peak of actual usage.
