Commitment to quality service (Service Level Agreement - SLA), we ensure monthly uptime of service as follows:

Service Commit Uptime Maximum Downtime (minutes)
Email Server 99,9% 43 minutes

The monthly uptime of the service is calculated by the formula:

43200 - Minutes interrupted X 100

If the monthly service uptime is less than the Uptime Commitment, we will compensate according to the service value of that month. The compensation ratio is as follows:

Uptime Compensation rate
From 99% to less than the rate of service commitment 20%
From 90% to 98.99% 40%
Lower 90% 100%

When the compensation condition is met, the amount of compensation will be added to your service period.

Compensation value includes only direct service value not exceeding the contract value and not include:
  • Initial initialization fees.
  • The license fees (License) are included with the monthly rental service or any given cycle.
