nginx - ddos ​​attack 502 appears on the homepage, please let the official optimize it quickly

Question

I suddenly tested it with ab today/Home page. I found that it was directly 502, please let the official optimize it quickly

Code:
ab -c 1000 -n 1000000 /

Answer 1

ab is just a stress test, which is a bit different from ddos. At least the first d is not satisfied.

Answer 2

Your test result is 502, but it does not mean that other users cannot access normally
