You're describing proper incident response but I fail to see what that has to do with the status page. They have core metrics that they could display on that status page without a human being involved.

IMO a customer-friendly status page would automatically display elevated error rates as "suspected outage" or whatever. Then management can add more detail and/or say "confirmed outage". In fact that's how the reddit status page works (or at least used to work), it even shows little graphs with error rates and processing backlogs.

There are reasons why these automated systems don't exist, but none of these reasons align with user interests.
