How is Uptime Calculated?

The uptime calculation is based on the following calculation (as defined in the Service Level Agreement):

"Uptime" means the total period in minutes during which the Service is available for access and use during this period.

“Uptime Percentage” means Uptime expressed as a percentage, calculated by the following formula:

Uptime Percentage = X /(Y–Z) × 100

Where:

X = Uptime

Y = Last 12 months period

Z = The duration (in minutes) of any SLA Exclusions* during these 12 months

*SLA exclusions are defined in the contract SLA (e.g. Scheduled maintenance, etc.)
