As part of a planned maintenance activity, which was supposed to have no impact on our service, a misconfiguration occurred at the firewall level. This misconfiguration caused a full data center service disruption. Upon identifying the misconfiguration, our engineers addressed the issue, successfully restoring the service.

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.)
