The Uptime Meter measures the availability of the installed base of Stratus^® ftServer^® systems worldwide. This meter is re-calculated every day, based on actual reported service incidents (see "Availability Calculation" below for details).

Availability Calculation

• Availability of the Stratus ftServer family is computed and updated daily based on all reported service incidents over the preceding 6-month period
• Both hardware-related and software-related incidents are included in this availability measurement
• Outages are only counted if there is an impact to production

Definition of Availability

• The fraction of a time period that a system is fully operational; for example, if a system is fully operational 100 hours per week, its availability is 100/168 = 60%
• Normally expressed in 9's; for example, "five nines" means that a system is fully operational 99.999% of the time, corresponding to less than 5.25 minutes downtime per year

Disclaimer

• The Uptime Meter is a measured indicator based on a statistically significant number of operational Stratus systems. However, the actual availability of any particular system may differ.
