Has the GCP security design document URL changed?

On Mattias’ "Security" slide in the "GCP Structure & Design" section he lists the GCP security document URL as:

https://cloud.google.com/security/security-design

That URL now seems to redirect to:

https://cloud.google.com/security/infrastructure/design

I’m assuming that’s just an update to the same document and location, but that might be something for a slide update at some point.
