It has a 'We are experiencing an issue with Google Cloud infrastructure components.' notice at the top though.

Gmail / GSuite / Youtube are not directly listed, though Firestore is and it's still green.

They added "We are experiencing an issue with Google Cloud infrastructure components" at the top, but everything is still green.

Are they unaware of which components have issues?

They know internally from the real status dashboards & real monitoring.

I think the issue is that this status page is maintained by hand, by humans, and updating it likely requires lots of communication and sign-off approvals, and trying to get numbers to decide whether an outage is big or only impacting a tiny fraction of users. Otherwise it'd probably always be red.

G Suite Status is all green with no warnings. https://www.google.com/appsstatus

FYI - these charts are more than likely updated by hand, by a person, with a bunch of deliberation and very high level approval (your actual SLA is probably based off of this person's call). At least that's how it was at another FAANG.

Good to know that Google+ is healthy

There are many warnings now.

Seeing that now. I like how the outage times are back-timed (11:57am est) to well before they posted anything about it.

That seems reasonable to me. You could argue that the posting should be quicker, but it's never going to be instantaneous. Back-timing is at least somewhat transparent.
