During the outage, 13 counties in the Dallas-Fort Worth area, including Collin County, were unable to answer 911 calls and temporarily routed incoming 911 calls to their non-emergency numbers.

MPD's Public Information Officer Carla Pertz said that the only difference between answering emergency calls from the non-emergency number is the inability to track a caller's location, so callers must know the location of their emergency in order to request the dispatch of emergency personnel.

According to CCSO Lt. Nicol Bristow, the outage was through the North Central Texas Council of Governments, or NCTCOG, which is responsible for 42 Public Safety Answering Points in 13 counties near the Dallas-Fort Worth Metroplex, according to their website where the agency has been releasing updates throughout the day.

"By 2:30 the network was back up and was monitored for an hour before being determined by our technicians that the network stability will allow us to return our PSAPs to normal operations one at a time," NCTOG staff said. "We are currently running at normal operations. The root cause has still not been identified."
