It would be most accurate to track the availability of every service
individually and the uptime of each connection individually. If you're
trying to calculate an aggregate systemwide uptime, what you might do is
get a median uptime of a representative sample of customers.

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)?
Thanks - Chris
