What does AWS EC2 DDOS protection shield throw when activated? HTTP(S) 503?

What does Amazon AWS EC2 DDOS protection shield throw when activated? HTTP(S) 503?

At which amount can this happen? 5000 - 10000 requests at "the same time"?

Is this public info and available somewhere?

Solution 1:

What Michael wanted to say is that if a DDOS attack is detected, let's say from IP X, an ACL is triggered which blocks all traffic from IP X to your service.

However, if you use AWS WAF to protect your web service, an HTTP status code would be 403 (Forbidden).

You should check the documentation and read through how the AWS Shield Advanced service works.
