Most services have a lot more systems than OpenAI and thus it is degraded performance when a few of them don’t work. Degraded performance isn’t a good thing, I don’t understand the issue with this verbiage.
Red - Entire services are down
Orange - Partial outage of services, some functionality completely down
Yellow - Functionality performance degraded and may timeout/fail, but may also work
Greed - Situation normal
Green - Situation normal
Yellow - An outage more severe than usual
Orange, Red - would trigger SLAs, so not possible and therefore not implemented
Black - Status page down too, served from cache, renders as Green
If certain functions of the service are completely unresponsive, i.e. close to 100% failure rate, that's not "degraded performance"---it's a service outage.
