A three hour-long E911 outage in Washington state April 10 will be investigated by the state Utilities and Transportation Commission, the UTC said. “We recognize this outage could have had serious implications for people and emergency responders across the state,” said David Danner, UTC chairman, in a news release (http://1.usa.gov/1tfu755). “Our investigation will look into the cause of the outage, (CenturyLink’s) emergency preparedness and response, restoration efforts, and communication with the public.” Enhanced 911 services began experiencing interruptions in Washington around 1 a.m. Thursday, April 10. CenturyLink said that E911 service was been fully restored statewide later that morning, the ETC said. CenturyLink said in a statement that about 4,500 911 calls failed during the outage between 12:36 a.m and 6:26 a.m. “The outage was due to a technical error in a third-party vendor’s call router, which prevented the system from properly processing calls,” the carrier said. “CenturyLink and its vendor partner have taken steps to implement an enhanced monitoring process and have addressed the router issue.” The outage occurred across 127 public safety answering points. “CenturyLink’s top priority is customer safety and reliable communications,” said Brian Stading, Northwest Region president. “We are working closely with our vendor partner to fully to understand this outage. At this time, we are confident that the 9-1-1 system is fully operational and stable."
