New York City leaders are investigating what went wrong after more than 1,700 calls to 911 failed on Tuesday morning in the Bronx.
From 3:13 a.m. to 10:19 a.m. on Tuesday, callers and dispatchers were unable to hear each other on certain 911 calls that were routed through a communications router at the Public Service & Government II facility on Marconi Street, according to city officials. The outage was first reported by the New York Times.
The issue was resolved just before 10:30 a.m. on Tuesday, and all calls have since been connected and responded to.
"We performed intensive overnight testing on the system and are monitoring the call delivery, traffic paths, and volume 24/7 in close coordination with our technical providers to ensure there are no additional service impacts," said Jeremy Edwards, Deputy Press Secretary for the Mayor's Office.
Approximately 5,659 calls to 911 came in during the impacted window. The city says after accounting for alarm systems and duplicate calls, they believe up to 400 people may have been unable to connect with an operator.
"Our investigation into the circumstances of this incident is ongoing. We are focused on understanding exactly what happened, ensuring that affected callers receive the appropriate follow-up and taking all necessary steps to prevent this from happening again," said Edwards.
Public Advocate Jumaane Wlliams is calling for a full investigation.
"In their most desperate hours, New Yorkers must be able to reach 911. We are deeply concerned about this breakdown. We need a full, expeditious investigation into what caused at least hundreds of calls to fail and a plan to ensure this never occurs again," Williams said.
