Law enforcement agencies across the country reported outages of their 911 systems Monday night, with the cause of the widespread disruption currently unclear.
Police departments from Nevada to Pennsylvania and Arizona to Minnesota, tweeted that their 911 systems were down beginning shortly after 6:30pm.
Multiple reports have since indicated that similar outages have occurred throughout Delaware, California, Delaware and Ohio as well.
The outage is impacting phone calls and text messages to 911, according to the reports.

The outages drew immediate scrutiny from the Federal Communications Commission, the agency responsible for regulating communications services.
FCC Commissioner Jessica Rosenworcel called for the situation to be investigated immediately.
'The one system we need to work all the time is 911,' she wrote in a tweet. 'The FCC needs to get to the bottom of this now and figure out what is going on.'
The blackout may be linked to a crash of Microsoft 365 services also on Monday night, which restricted user's access to Outlook.com, Office.com, Power Platform, Dynamics365, and Microsoft Teams including Teams Live Event.
Earlier Monday evening, the city of Redmond, Washington, where the software giant is based, noted city phone lines and email accounts were down due to the Microsoft outage, which started after 5pm ET.
On a status page for its cloud services, Microsoft acknowledged the widespread systems issue and said 'Any user may experience access problems for Microsoft 365 services.'
