Police departments in several states reported interruptions to the 911 service on Monday evening.
The Minneapolis Police Department said 911 lines “are not operational nationwide” but provided few other details. The problems extended to departments in many states, including Minnesota, Delaware, Arizona, Indiana, Colorado, and Pennsylvania.
“ATTENTION: The 911 lines are not in operation nationwide. This is for phone calls and text messages. For police, fire, or emergency medical assistance in Minneapolis, please call 612-348-2345. We will advise you when this problem is resolved, “said the department.
The Delaware State Police said their shipping centers had experienced a “statewide shutdown”
“The Delaware State Police dispatch centers are now up and running with 911 calls,” the Delaware State Police said in a statement. “When you call 911 and receive a busy signal or a recorded message, callers are prompted to text 911 and enter your emergency in the message field or use the non-emergency phone numbers.”
The failure seemed to resolve itself in many places within minutes.
The 911 outages were immediately examined by the Federal Communications Commission, the agency responsible for regulating communications services. FCC Commissioner Jessica Rosenworcel called for an investigation into the situation.
“The only system we have to work on all the time is 911,” Rosenworcel wrote on Twitter. “The FCC now has to get to the bottom of it and find out what’s going on.”
The cause of the business interruption was not immediately clear. However, the departments reported problems due to an ongoing outage affecting Microsoft 365 services, including Outlook and Office.
On Monday evening, the city of Redmond, Washington discovered that the city’s phone lines and email accounts were down due to the Microsoft 365 outage. Microsoft’s headquarters are in Redmond.
Microsoft did not immediately return a request for comment.
