A recent 911 service disruption in multiple Canadian provinces lasting about 90 minutes was due to an undisclosed software flaw in Bell’s system, the company stated in a report on Friday. The incident, which occurred at 3:13 a.m. ET on Sept. 17, affected regions including Manitoba, Ontario, Quebec, New Brunswick, Nova Scotia, and Prince Edward Island.
Bell clarified that the outage was not a result of a cyber attack or any deliberate changes. The glitch impacted components of Bell’s advanced 911 system, known as NG9-1-1, which aims to enhance emergency response by providing detailed information to responders before they arrive at a scene.
Service was restored at 4:40 a.m., with Bell implementing a permanent fix. While the majority of calls during the disruption were handled by backup systems, legacy voice calls routed through older systems to next-gen call centers were missed.
Fortunately, no critical safety incidents resulted from the missed calls. Bell has taken steps to prevent a recurrence of such incidents and is committed to enhancing emergency calling services for public safety.
According to the report, initial alarms at the onset of the outage failed to trigger a crisis response promptly. The issue was resolved after a delay, prompting Bell to install additional monitoring mechanisms for better oversight. The company is conducting a thorough review of its systems and sharing insights with other service providers for improvement.
In the interest of security, Bell withheld specific details about the software flaw to prevent potential exploitation by hackers. The company emphasized the importance of safeguarding the public interest and the integrity of the 911 network.
The 911 service in Canada is linked to regional legacy telecom providers, with Bell handling service in several provinces. Holly Barkwell from NENA acknowledged the resilience of Canada’s emergency system but highlighted the inherent challenges of technology.
The CRTC has mandated the decommissioning of legacy 911 systems in Canada by a specified date, with recent extensions granted to ensure a smooth transition.
