What Are the Impacts When QPS Exceeds the Allowed Peak Rate?
If the QPS specifications you select cannot handle the daily peak traffic of protected website or application services, WAF stops protecting your website. This will cause traffic limiting, random packet loss, automatic bypassing of WAF. As a result, your services may become unavailable, frozen, or respond very slowly for a certain period of time.
Table 1 lists the QPS specifications supported by each WAF edition.
