(KLZA)--The Nebraska Public Service Commission has closed its investigation into three separate 911 outages involving Windstream and opening a new department complaint against the telecommunications carrier.

The investigation involved three separate Windstream service disruptions which occurred on September 2 & 3, November 28, 2023, and January 13, 2024.

The department complaint process allows the Commission the opportunity to asserts its authority under Nebraska law to issue punitive sanctions which may include assessing administrative fines for violation of Commission regulations.

A hearing date on the Windstream complaint has been scheduled for August 27 & 28.

The September 2nd and 3rd outage included a multi-hour disruption of 911 service that resulted from a system-wide telecommunications outage experienced by Windstream customers in southeast Nebraska.

The November 2023 Windstream Outage appears primarily to have impacted the delivery of 911 calls and non-emergency telephone service to public safety answering points in the Southeast Region of PSAPs. Fortunately, according to the information available as of the date of this Order, the November 2023 Windstream Outage was resolved, with full service restored, in less than an hour.
