It depends whether the outages are overlapped or not. If the outages are not overlapped then that is indeed how you do it since some of your services being unavailable means your service is not fully available.
There's limits to that type of logic. Otherwise, as long as a single elevator or water fountain in any Google satellite office were out of order, would you consider Google "not fully available"?
I mean, there's a big difference between primary Git operations being down and Copilot being down. Any SLAs are probably per-service, not as a whole, and I highly doubt that someone just using a subset of services cares that one of the other services is down.
Copilot seems to be the worst offender, and 99% of people using Github likely couldn't care less.
