Maintenance Notification


Dear FiberNET Customer,   

We will be performing network maintenance starting at 12:01 AM Wednesday September 14, 2022. The maintenance will be to complete an efficiency modification to our core routers as well as controller and firmware updates for our commercial wireless offerings. We do not expect a lengthy downtime during this maintenance window, however, it could potentially require unforeseen brief periods of service interruptions as well as a potential for longer intermittent outages throughout the window. This has the potential to affect all services for brief periods of time. Video customers should not reboot set top boxes.   

The maintenance will begin at 12:01 AM and should be complete by 6:00 AM, of the same morning. Please note, we will make every effort to minimize any and all interruptions.   

We appreciate your understanding in this matter and thank you for patience!
