AWS WAF gets disassociated without any warning

Question

AWS WAF can get disassociated without any warning. Could we please get at least an email? Something like:
[Attention Required] WAF disassociated you are now exposed to all the internet.

We are using AWS Load Balancer Controller and the WAF stopped working without notice until we found this:
https://github.com/kubernetes-sigs/aws-load-balancer-controller/issues/2219
But even now I cannot guarantee that the WAF will stay up...

I’ve never seen this myself. I have seen a WAF ACL applied to many ALBs but never seen a WAF disappear from an ALB.

How are you associating them?

You can check the Cloud Trail logs to see why ALB is getting disassociated from WAF. **DisassociateWebACL** is the API that disassociates the specified regional application resource from any existing web ACL association. Additionally, check if you have Firewall Manager (FMS) thats controlling the WAF integration. If yes, review the rules that you have in FMS that might be preventing the association of ALB to WAF.

Through the aws management console. But this is not the point.

Any state changes on a WAF should trigger an email notification. If you agree, can you please upvote my question so that it gets seen?

Thanks in advance
