Unscheduled Maintenance Notification
Update - System Maintenance – Progress Update

As part of our ongoing maintenance, NUSO has completed its initial system updates and adjustments. We are now coordinating with our technology partners on additional updates, which will be reviewed and tested prior to deployment.

The previously communicated temporary limitations involving certain Microsoft Teams integrations and file upload functionality within Green UC and select legacy Contact Q installations remain in place.

Core voice services continue to operate normally. We will provide further updates as maintenance progresses and functionality is restored.

We appreciate your continued patience.

Update - System Maintenance Update

We would like to provide additional clarity regarding the ongoing maintenance and its impact on certain platform functions.

1. Microsoft Teams Integrations

Due to unscheduled maintenance being performed by one of our technology partners, CRM integrations with Microsoft Teams, including NUSO Bridge for Teams and Operator Connect, are experiencing temporary service limitations. We will provide further updates as maintenance progresses.

2. Administrative Portals and File Uploads

We would also like to clarify the scope of the previously announced system maintenance. The impact is limited to certain file upload capabilities within our Green UC platform and select legacy Contact Q installations. Functions such as CSV imports, voice file uploads, and similar features may be temporarily unavailable.

All other administrative portal functionality remains available.

These limitations are isolated to the affected functions, and no interruptions to core voice services are expected.

We appreciate your patience and understanding as we work to restore full functionality.

Update - We are continuing to work on a fix for this issue.
Oct 21, 2026 - 07:57 CDT
Identified - We are currently performing maintenance across select systems to support ongoing platform improvements. During this time, access to certain administrative portals and network management functions may be temporarily unavailable.

No interruptions to active services are expected. We appreciate your patience and will provide updates as maintenance progresses.

Northeast Fiber Cut
Resolved - A card replacement has been completed within the Verizon network.
Oct 8, 14:31 CDT
Update - Verizon’s Director has confirmed that a technician has been dispatched to the same location investigated yesterday and is currently on site.

At this time, Verizon has not confirmed whether the affected equipment cards have been replaced. The field technician has, however, identified a light-level issue originating from the far end of the fiber span.

To further isolate the fault, Verizon is dispatching an additional technician to the far-end location, with an estimated arrival time of approximately one hour.

SERT will continue working with Verizon to confirm whether the equipment cards were replaced and to determine whether the light-level issue was identified following that replacement effort or whether the card replacement had no impact on service restoration.

The next update is expected at 2100 GMT.
Oct 7, 15:25 CDT
Update - During the maintenance window, offnet field technicians cleaned, scoped the fibers and OTDR tested the common fibers on DWDM, confirming that the OSP plant fiber paths are in good condition. Despite further troubleshooting with Transport the DWDM issue remains unresolved. Tier 2 has been engaged to evaluate the situation and develop a detailed action plan.

The work around from the NUSO side still remains in place while Verizon further investigates
Oct 6, 08:15 CDT
Update - NUSO has rerouted all traffic that can be moved away from the affected Verizon network path. Following these routing changes, inbound calling is operating normally across the areas where alternate routing is available, and related trouble reports have significantly subsided.

A limited number of smaller geographic areas remain affected where alternate routing capabilities are not currently available.

Verizon has identified the underlying issue as a fiber cut and has advised that intrusive testing of the affected fiber will begin at approximately 8:00 PM ET this evening.

At this time, we are marking the broader service impact as cleared and will continue monitoring network performance. NUSO Engineering will remain engaged with Verizon as they perform testing and work toward full restoration of the affected fiber facilities.

We will provide additional updates if conditions change or once Verizon completes its repair activities.
Oct 5, 13:26 CDT
Monitoring - A fix has been implemented and we are monitoring the results.
Oct 5, 10:36 CDT
Investigating - We are currently experiencing intermittent inbound call failures affecting portions of the Northeast region.

Our teams have identified the underlying issue as a fiber cut within the Verizon network. NUSO has rerouted traffic around the affected network path, and calls should now be completing normally without interruption.

We will continue to monitor call completion and network performance while Verizon investigates and repairs the underlying fiber issue.

Additional updates will be provided as they become available.
