It's 75 minutes to _communicate_ the message to customers. Definitely internal teams were ahead of this before it was posted to the AWS Health Dashboard. Status Page posts are lagging indicators of incident progress.
I work in an incident management team where the turnaround from "we've decided to take x action, to y metric shows it is working, to z is posted on the status page" can be 1-2 minutes.
It is possible with professionals, institutional knowledge, drills, and good tools.
