On June 15, Chelan PUD's fiber network experienced a service disruption that impacted approximately 17,000 to 19,000 customers. The outage occurred between 5:39 p.m. and 5:53 p.m.

Chelan PUD has been working closely with our vendor, Nokia, to determine the cause of the outage. Based on the event logs and data, it has been identified as a software issue affecting the distribution hardware that connects to Optical Network Terminals (ONTs). The ONT is the fiber device installed at your home that connects to your router and delivers your fiber internet service. 

What We’re Doing

Nokia’s Research and Development team is currently preparing a new software update to correct the issue. We expect to receive this update by the end of June. 

After Nokia provides the updated software, Chelan PUD will schedule a planned maintenance window to apply the update to our Optical Line Terminal (OLT) shelves, which are the core components of our network that manage internet connections to customer ONTs.

In the meantime, some customers may experience intermittent service interruptions. We are working with Nokia to explore whether manual interventions can be performed during off-peak hours to help reduce the risk of further disruptions until the software upgrade is fully implemented.

We’ll continue to keep you informed as we receive further updates. Thank you for your patience and continued support.
