What Can I Do If the Website Traffic Exceeds the WAF Service Request Limit?

If your website normal traffic exceeds the service request limit offered by the edition you select, website traffic forwarding may be adversely affected.

For example, your website traffic may be limited, packets may be discarded randomly, and WAF may be bypassed automatically. Your website services may be unavailable, frozen, or respond very slowly.

If website traffic exceeded the WAF service request limit, WAF does not send alarm notifications. If the QPS limit supported by the WAF edition you are using is exceeded, WAF will send alarm notifications once it detects attacks on your website. For details, see Enabling Alarm Notification

In this case, upgrade your edition or buy extra QPS expansion packages.

For details about how to upgrade WAF, see Changing the Edition and Specifications of a Cloud WAF Instance.
