An outage lasting almost 90 minutes affected 911 services in multiple Canadian provinces last month, as Bell disclosed a software glitch as the cause in a recent report. The incident, which struck Manitoba, Ontario, Quebec, New Brunswick, Nova Scotia, and Prince Edward Island at 3:13 a.m. ET on September 17, was attributed to an unforeseen bug within Bell’s software system.
Bell clarified that the disruption was not a result of a cyber attack or any intentional changes. The issue impacted components of Bell’s NG9-1-1 system, intended to enhance emergency response by enabling the public to provide detailed information to dispatchers before first responders arrive.
The company managed to identify and resolve the root cause, restoring services by 4:40 a.m. after 87 minutes. A permanent solution was implemented later that morning to prevent similar incidents. Although most calls were successfully handled by backup systems during the outage, a few “legacy” voice calls were missed if directed to call centers still reliant on older technology.
Fortunately, none of the missed calls led to critical safety incidents. Bell, emphasizing its commitment to emergency services’ reliability and improvement, mentioned that the September 17 outage was the first of its kind since the NG9-1-1 system’s launch in early 2022.
The report also highlighted that initial alarms during the outage did not trigger the expected response promptly, delaying the resolution process. Bell has since enhanced monitoring mechanisms to prevent recurrence and is conducting a thorough review of its system to address any vulnerabilities.
Due to security concerns, Bell redacted specific details regarding the software flaw and wider system information in the public report, citing potential risks of exploitation by hackers. The company underscored the importance of safeguarding the 911 infrastructure and public interest.
In Canada, 911 services are managed by regional legacy telephone providers, with Bell overseeing services from Manitoba to the Atlantic provinces. The CRTC has mandated the decommissioning of all legacy 911 systems in Canada by March 31, a deadline extended by two years in early 2025.
