After an afternoon of 911 calls being disconnected or delayed, the Department of Emergency Management announced at just after 4 p.m. that the issue has been resolved.
The Department of Emergency Management wrote in a 12:21 p.m. post on X that “911 is still operational” after a “reported AT&T/Xfinity/Comcast cell outage.” The post goes on to advise residents to try Wi-Fi calling if they are unable to reach 911.
Jackie Thornhill, a spokesperson for the Department of Emergency Management, said the department had received preliminary reports that users of multiple cellular providers were either having their 911 calls disconnected or the calls were only going through with significant delays.
Reported AT&T/Xfinity/Comcast cell outage. 911 is still operational. If not able to call, enable wi-fi calling, connect with a friend to make calls, or use text to 911.

If your phone is still not able to make a 911 call, then try connecting to a Wi-Fi network and enable Wi-Fi… pic.twitter.com/yjhPGx1V0X
An internal San Francisco Police Department email sent shortly after told staff that “911 is not working properly at this time.” It advised that “stations may receive an influx of 911 calls.”
It is not yet clear what, exactly, went wrong and how many would-be 911 callers were affected.
