It’s a small DDoS

The number of connections are usually between 1k to +100K. We tested our Apache httpd 2.4 Server on CentOS 7 with 7K zombie bots. The CentOS server and the Apache httpd server both use default config.

Did they kill the server

The Zombie DDoS botnet interrupted the service on the web server because our monitoring probe got 42 failed requests.

Can I really block that?

We ran the same test with DDoS protections against Zombie botnets and we can see an average response time of 77 ms with DDoS protections compare to 2,514 ms without DDoS protections. There is a little bit of latency at the beginning before the DDoS is fully mitigated and the service stabilizes by itself in less than 5 seconds without human intervention.
