Can DDoS scrubbing (DDoS清洗) completely eliminate the impact of all types of DDoS attacks?

While DDoS scrubbing is highly effective, it cannot completely eliminate the impact of *all* types of DDoS attacks under every circumstance. Very sophisticated, low-and-slow application-layer attacks that mimic legitimate user behavior can be challenging to filter without impacting genuine users. Furthermore, internal infrastructure vulnerabilities or insufficient server resources might still cause issues even if the network perimeter is protected. DDoS scrubbing is best viewed as a critical component of a broader, multi-layered security strategy rather than a standalone panacea.
