I am a Product Manager in the Platform Engineering team.
Our apologies for the lack of communication during the previous outage. As you correctly pointed out, we were suffering an outage and our usual channels were not used to communicate status. You are also correct in that our communication during outages has been (to be polite) uneven lately.
We apologize and are working to do better in the future.
We are currently in the process of revising our outage communication process to make it more streamlined and consistent. Our plan is to roll out a new status page similar to what many other websites use; this will replace our other mechanisms.
As of May 2022, we implemented a way to update StackStatus directly from our incident management tool. We used to manually log in to Twitter which was a lot of friction especially during an outage, so this should improve the overall process.
