Thought: There should be an official Google status dashboard for "free" (paid for via personal ad targeting metadata) services like Search, Gmail, Drive, etc. With postmortems, too. Probably won't happen unless it's mandated by law, though.
Free and paid versions of Google services share pretty much the entire stack, so the Google Workspace (previously G Suite) status page works just fine – https://www.google.com/appsstatus#hl=en&v=status.
Existing dashboards showed the services as being up, since the frontends worked fine - as long as you did not try to authenticate.
