What happened?

Our frontend configuration got updated with the wrong routing (redirecting) rules and this resulted in some stores experiencing website not found or certificate errors.

Why just some stores?

We run high availability configuration where traffic is not served from only one server, but multiple. While only one server experienced the issue others were serving traffic normally.

What are we going to do to prevent this in the future?

We added additional checks that will test the applied rules before deployment.
