Scheduled -
Reason:
As part of our infrastructure lifecycle management, we will replace the current firewall platform. The existing hardware has reached end of support and will be replaced with new hardware running the latest supported firmware to ensure continued security, stability, and performance.
Impact:
A service interruption is expected during the firewall cutover. All non-voice services will be unavailable for approximately 5–10 minutes. Services that depend on web connectivity or web service integrations, including IVR and Contact Center solutions, will experience disruption during this period. Following the cutover, additional validation and testing will be performed, during which a limited risk of intermittent service degradation may exist for up to 1 hour.
Checks:
A comprehensive post-change test plan will be executed to verify firewall functionality, network connectivity, and the availability of impacted services.
Rollback:
- Disconnect the new standby firewall
- Move network connections from the new firewall back to the existing firewall
- Reconnect services at the standby location
- Validate service restoration
User actions:
No user actions are required.

Reason:
Our vendor will perform infrastructure maintenance and server patching on the OCC Cloud platform to ensure continued platform stability, security, and performance.
Impact:
Every effort will be made to perform the work in the background and minimize disruption. However, during the maintenance window, there may be brief periods where end users are disconnected while backend services are being updated. If this occurs, users should be able to reconnect and continue working normally without further impact.
Checks:
- Validation of infrastructure and backend services after maintenance completion.
- Verification of application connectivity and service availability.
- Monitoring of platform health and performance throughout the maintenance window.
Rollback:
Should any unforeseen issues arise during the maintenance, the changes can be rolled back following standard operational procedures to restore service stability.
User actions:
No action is required from agents or end users before or after the maintenance.
