Subject: [AFMUG] Uptime Calculation?

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
