A public IP suffered DDoS attacks
Last updated: 2024-07-01 11:40:46
Problem
DDoS attacks overwhelm your business with massive amounts of traffic, exhausting the server performance and network bandwidth and thus crashing down the server.
Common Cause
Tencent Cloud’s free basic protection capability (2 Gbps) is not enough to defeat the DDoS attacks.
Solutions
Replace a public IP (expedient)
When attackers start DDoS attacks against your specific business IP, you can avoid the blocking trouble temporarily by replacing the attacked IP with a new one. However, the new IP is still exposed to DDoS attacks, causing potential business interruptions.
Get an Anti-DDos product (recommended)
By getting an Anti-DDoS instance, you can improve IP protection capability to defend against large traffic attacks. If the Anti-DDoS Pro instance of the region is unable to defeat massive attack traffic, you can use an Anti-DDoS Advanced instance with greater protection capability as needed.
Directions
Replace a public IP (expedient)
The use limits are as follows:
Each account can change public IP addresses in the same region a maximum of 3 times per day.
Each instance can only change its public IP once.
The old public IP will be released after it is replaced.
Get and set an Anti-DDoS product (recommended)
