Post-Maintenance Incident Summary – CloudCore (December 10, 2025)

‌

Maintenance Window: Dec 10, 2025 at 12:00 AM PST
Status: Resolved

During the scheduled CloudCore maintenance to migrate remaining OMC VMs to Azure managed disks, an unexpected TR-069 service issue occurred after the environment switch. This resulted in some eNBs and CPEs losing management connectivity.

Because TR-069 connectivity supports SAS operations, CBRS devices with SAS enabled experienced service disruption (RF mute) while TR-069 communication was unavailable. Once the issue was corrected, devices gradually reconnected to CloudCore.

Root Cause

A required cache initialization step was not executed during the startup of the upgraded OMC environment. This caused a portion of devices to be temporarily mapped into a default profile, interrupting normal TR-069 and SAS workflows.

Current Status

• TR-069, SAS, and OMC services are fully restored.
• Most devices have automatically reconnected.
• A small number of devices may remain offline until rebooted.

Customer Action

If any devices remain offline in CloudCore, please reboot or power-cycle the device to force a new TR-069 session.
