3. System Environment

3.1 General

This chapter provides a description of the System Environment as provided by Viadesk to Customer.

3.2 Network

Viadesk will see to it that all necessary infrastructure for safe and reliable Internet connectivity will be present. This consist, among others, of the following:

3.3 Software

The following software, among others, is installed on the server arranged for Customer:

The responsibilies of Viadesk include keeping the software up to date proactively. This will take place within the described Maintenance periods.

3.4 Capacity

3.5 Back-up

Process-data and system settings are safeguarded by means of a back-up or replication system, such that the RPO and RTO time agreed in paragraph 4 can be realized. The Back-up is exclusively intended to restore the service in the event of an Interference.

4. Availability

4.1 General

Viadesk strives to keep the System Environment available at all times. If an Interference reduces Availability, Viadesk is obliged to resolve the Interference within the periods agreed upon in this SLA. Viadesk commits to regular control and thorough Maintenance of the System Environment it uses, and will see to it that enough capacity is available so that this doesn't cause Interferences during more than normal use.

4.2 Availability

Viadesk delivers an Availability of 99,9% a month. This implies an RTO time of 43 minutes.

The Availability is calculated as follows:

Availability = (the amount of minutes of Dropout / total minutes per month) * 100%

Dropout occurs when the Application Software is unusable for all Users as a consequence of an unplanned event. If the Application Software is only unusable for a few Users, or does not function correctly, this is considered an Interference whereby the service itself is still considered Available. The responsibility of Viadesk with respect to Solution Time does not apply when:

Viadesk does not warrant ("guarantee") that communication through the Internet or that a connection with the System Environment from a different server of workstation, is possible at all times.

In the event of a system environment Dropout associated with data loss, an RPO time of 24 hours applies.

4.3 Monitoring and logging

During all Service Windows, the Service Window is automatically monitored by Viadesk and/or its suppliers. In case of an Interference, the administrators will intervene proactively. During Interferences, engineers will be stand-by 24 hours a day, 7 days a week.

4.4 Planned Maintenance

During preventive maintenance activities, Viadesk aims to keep any observable influence on the service for the user to the minimum. Nevertheless, it is possible that the Application Software will be unavailable to Users in whole or in part. To prevent this as much as possible, the following measures are employed:

Viadesk will announce Planned maintenance outside of Service Window 2 at least 5 days in advance via email and Twitter: @ViadeskSupport (

Viadesk will announce major releases of the Application Software at least 5 days in advance via email to Customer's Contact Person.

4.5 Emergency Maintenance

Emergency Maintenance may be necessary when circumstances require immediate intervention. Emergency Maintenance is included in calculating the Availability.

5. Communication
