Twin Harbors emergency service providers reported no issues resulting from the loss of 911 service when CenturyLink’s network was “interrupted” Thursday.

Aberdeen Police Chief Steve Shumate said he was not aware of any complications when contacted Friday, and sources with the South Beach Regional Fire Authority likewise did not report any issues as a result of the service interruption.

Nikki Wheeler, a CenturyLink spokeswoman, called it a “network event” Friday afternoon.

“We take all service interruptions seriously and have had teams working around the clock to restore affected services,” she said. “We have made substantial progress in restoring and stabilizing services across the network over the last several hours. We remain focused on resolving all remaining issues. At this time, where CenturyLink is the 911 service provider 911 calls are completing.”

Calls to 911 during the interruption in service were greeted with a rapid busy signal. As of noon Friday, the majority of the Twin Harbors reported having 911 service restored.

The Washington State Utilities and Transportation Commission released a statement Friday, stating in part, “The state Utilities and Transportation Commission announced that it will open an investigation into this week’s statewide enhanced 911 service outage. The investigation will look into the cause of the outage, the company’s emergency preparedness and response, restoration efforts, and communication with the public.”

The Utilities and Transportation Commission is the state agency in charge of regulating land line telephone companies operating in Washington.

The commission submitted a list of alternate 911 emergency numbers in case regular 911 service is interrupted.

• Grays Harbor County: 800-281-6944 or 360-533-8765. These numbers will connect you with emergency services throughout the county.

• Pacific County: Text 911 or in South Bend call 360-875-9397, in Long Beach text 911 or call 360-642-9397.

Emergency managers recommend programming these alternative numbers into your phones should 911 service be interrupted in the future.

Federal Communications Commission Chairman Ajit Pai announced Friday that the agency has launched an investigation into the nationwide CenturyLink outage, which has affected 911 service for numerous consumers across the country.

“When an emergency strikes, it’s critical that Americans are able to use 911 to reach those who can help,” said Pai. “The CenturyLink service outage is therefore completely unacceptable, and its breadth and duration are particularly troubling.”

Pai’s statement continued, “I’ve directed the Public Safety and Homeland Security Bureau to immediately launch an investigation into the cause and impact of this outage. This inquiry will include an examination of the effect that CenturyLink’s outage appears to have had on other providers’ 911 services.”
