Probably requires manual updates. It seems like more and more places have moved to this paradigm now that status pages are tied to SLAs which are tied to money. One might call it the politicization of status pages.
Or you get weasel-worded out of it. I had a cloud provider deny a service credit; the SLA stated that the service was only out of SLA if it didn't return 2xx. Well, the API returned "2xx Accepted — your request is being processed", and you could use the API to query the job, and the job … never finished or made any progress at all. But the API returned 2xx the entire time, so that was "within SLA".
I don't think it's politics (maybe AWS's is, but GCP wasn't IMO), it's really a function of "in large scale software systems things are constantly failing in all sorts of ways, and it's really hard to output a meaningful automated signal that things are broken. Sure you can set up pingdom type health checks on every endpoint, but even then you're not necessarily guaranteeing that things are working properly.
