Why Is the Access from the Internet Abnormal?
HUAWEI CLOUD Anti-DDoS will trigger a black hole to block access from the Internet within a time period when detecting an ECS is under volumetric flood attacks.
Anti-DDoS provides a 2 Gbit/s DDoS mitigation capacity for free, and its maximum mitigation capacity can reach 5 Gbit/s (depending on the available bandwidth of HUAWEI CLOUD). Traffic that exceeds 5 Gbit/s will be routed to a black hole. For applications threatened by attack traffic larger than 5 Gbit/s, it is a better choice to purchase the Advanced Anti-DDoS service on HUAWEI CLOUD to expand protection capacity.
