If I were in your shoes, I wouldn't expect one, and if one ever does get published, be suspicious of it. VERY suspicious. Because it's likely missing critical information and/or some portion is likely fictitious to some degree. I mean, this is a company that can't even update its own system status dashboard truthfully, so don't expect any degree of honesty or accountability here.
Automated issue notifications get pushed to the Personal Health Dashboard for AWS and to my knowledge, GCP doesn't have automated status updates available to customer. (But AWS requires a support plan to gain access to their PHD, so it can be considered inaccessible to many as well).
If I was starting a project from scratch now, I'd certainly explore other cloud providers, which is not something I would've said 3 years ago. Their blatant lying is definitely going to cost them in the long run.
I saw notifications in the AWS Personal Health Dashboard pretty very early into the issue. Did you see something different?
Also, I've seen issues logging into the default console a lot, so I keep one of the backup endpoints bookmarked. Might come in handy for you too!
