Description

Scheduled Maintenance – UK Clusters We are carrying out a short maintenance activity on our UK (Dualcom Pro, Gemini) platforms. During this window, UK clusters will be placed into flood mode to prevent unnecessary signalling during controlled work. Expected impact: Path failures will be held and not delivered during the maintenance window. Commissioning and test alarms for newly installed units will not be processed until the maintenance has completed. No customer action is required. Our engineers will closely monitor the platform throughout, and normal service will resume once the activity is complete. Further updates will be provided here as needed.
