Planned Maintenance Notification - CR00014178P4 - Planned Maintenance

Description

Scheduled Maintenance – EU Clusters 20th May We are carrying out a short maintenance activity on our EU platform. During this window, all EU clusters will be placed into flood mode to prevent unnecessary signaling during controlled work. Expected impact: Path failures will be held and not delivered during the maintenance window. For new installs, delivery of path failures and restores will not be submitted to the ARC until the maintenance is completed and the system is out of Flood. No customer action is required. Our engineers will closely monitor the platform throughout, and normal service will resume once the activity is complete.
