An outage affecting 911 services across several Canadian provinces for nearly 90 minutes last month was attributed to an unknown flaw in Bell’s software, as per a report released by the company on Friday. The incident, which occurred at 3:13 a.m. ET on Sept. 17, impacted regions including Manitoba, Ontario, Quebec, New Brunswick, Nova Scotia, and Prince Edward Island.
Bell clarified that the disruption was not a result of a cyber attack or any deliberate changes but was caused by an underlying software problem within its NG9-1-1 system. This system is designed to enhance emergency response by enabling the public to provide detailed information to dispatchers.
After identifying the root cause, Bell managed to restore service at 4:40 a.m., implementing a permanent solution to prevent similar incidents in the future. The company acknowledged that some calls were missed during the outage but stated that no critical public safety incidents occurred as a result.
Despite initial alarms failing to trigger a crisis response, Bell’s response team resolved the issue within a short span after being alerted by a separate monitoring system. The company is conducting a thorough investigation into the alarm failures and has put additional monitoring measures in place to prevent future incidents.
In the interest of security, specific details regarding the software flaw and broader system information were redacted from the publicly released report to mitigate potential risks of exploitation by hackers. Bell emphasized the importance of safeguarding the 911 infrastructure to protect public safety.
The Canadian 911 system, which is interconnected with regional telephone providers, saw Bell overseeing services in multiple provinces, with other regions being serviced by different providers. Industry experts highlighted the resilience of Canada’s 911 system, acknowledging that while no system is flawless, efforts are continuously made to enhance emergency response capabilities.
The CRTC has set a deadline for the decommissioning of legacy 911 systems in Canada by March 31, 2027, extending the original deadline by two years to allow for a smooth transition.
