A number of U.S. law enforcement agencies said their 911 lines were not operating Monday evening.
In a tweet Monday evening just before 8 p.m. ET, the Minneapolis Police Department said the outage was “nationwide.”
“This is for phone calls and text messaging,” the service said.
Just after 9:30 p.m. the force said the system was “back up and working again,” adding that the “nationwide outage” had been fixed.
In Nevada, the Washoe Sheriff department said 911 systems were down in a number of areas including Washow County, Reno and Sparks.
“Rerouting is unconfirmed at this time,” the tweet reads.
Similarly, the Delaware State Police said it’s dispatch centres had experienced “a state wide interruption in service.”
However, an update posted approximately an hour later said the system was operational again, and 911 calls were being received.
Meanwhile, in Minnesota the Hennepin Sheriff’s department said it had experienced the outage too, but that the service was back up and running.
In a tweet just after 8 p.m. ET, the Sheriff’s office said “functionality has been restored.”
“Please do not call 911 to test the system, as it may interfere with real emergency calls getting through,” the tweet reads.
In Arizona, the Oro Valley Police said it too had experienced the outage, but that the issue had been fixed.
“911 is back up for all agencies,” the tweet read.
It was not immediately clear what was causing the outage, or if functionality had been restored to all affected forces.
