So this can vary as you are probably gathering …
But one thing that is typically consistent is that scheduled maintenance does not count towards downtime. The way I’ve seen it done with lots of providers, especially WISP’s, is to measure from the tower site back to your network and from your network to the Internet. I know that’s pretty generic but basically it measures everything except for individual end users.

I suppose my goal is to provide meaningful information that can be compared to other providers. It definitely seems uptime should represent total service time / total expected time. A further question... do providers here consider scheduled maintenance to be downtime?

When figuring uptime, is a partial outage normally calculated differently than a complete outage? For example, an outage affecting 10% of customers for 1 hour out of 100 hours... is that typically considered 99% uptime (any outage is considered a full loss) or 99.9% uptime (only a 10% loss, so only 10% downtime)?
