This topic describes the blackhole filtering thresholds and blackhole filtering duration in Cloud Web Hosting.
Background information
Cloud Web Hosting provides shared Cloud Web Hosting instances and exclusive Cloud Web Hosting instances.
Blackhole filtering thresholds
The following table lists the blackhole filtering thresholds for exclusive Cloud Web Hosting instances in different regions.
Region | Blackhole filtering threshold |
---|---|
China (Hangzhou) | 5 Gbit/s |
China (Qingdao) | 5 Gbit/s |
China (Shenzhen) | 2 Gbit/s |
China (Beijing) | 2 Gbit/s |
China (Shanghai) | 2 Gbit/s |
China (Hong Kong) | 500 Mbit/s |
US (Silicon Valley) and US (Virginia) | 500 Mbit/s |
Singapore | 500 Mbit/s |
Blackhole filtering duration
- The duration of attacks. If attacks continue for a long time, the duration of blackhole filtering is extended.
- The frequency of attacks. If an asset experiences attacks for the first time, the duration of blackhole filtering automatically decreases. If an asset experiences frequent attacks, the asset has a high probability to encounter continuous attacks, and the duration of blackhole filtering is automatically extended.
If you want to obtain higher DDoS mitigation capabilities, purchase an Anti-DDoS Pro instance or Anti-DDoS Premium instance that provides up to 300 Gbit/s of basic protection bandwidth each day. For more information, visit the product page of Anti-DDoS.
