Description

Dear Customer, As part of our ongoing efforts to maintain optimal service performance and resilience, we would like to inform you of scheduled maintenance activity: What’s Happening? On Wednesday, 21 January 2026, CSL Infrastructure will: Transition traffic from backup links back to the primary links. Replace a failed network router during the same maintenance window to restore full network resilience. This follows mitigation measures implemented on 22 December 2025, when two of our European sites were impacted by an upstream provider issue. During that event, traffic was rerouted to backup links to restore services successfully. Customer Impact At 10:00 AM (UK time) on 21 January, CSL will enable filters and smart reporting to hold path failures during the transition. These filters will be disabled once maintenance is complete, after which smart reporting will resume normal operation. No service impact is expected for the following services during this activity: CSL DualCom Pro UK Emizon UK Gemini Gradeshift UK CSL Connected WebWayOne During the maintenance window: New device installs/commissioning for DualCom Pro units will not be possible. Device polling and alarm delivery will continue to operate normally throughout the maintenance. At the end of the maintenance window: Events held in smart reporting and filters will be released. We will update our status page to advise when we are about to do this. ARC’s may receive some device failure and restore notifications that were being held in smart reporting prior to the maintenance as a result.
