An unexpected software glitch in Bell’s system caused a 911 outage lasting around 90 minutes across multiple Canadian provinces last month. Bell’s report to the Canadian Radio-television and Telecommunications Commission (CRTC) clarified that the incident, which occurred at 3:13 a.m. ET on Sept. 17, was not a result of a cyber attack or any planned changes.
The glitch impacted components of Bell’s NG9-1-1 system, disrupting emergency services in Manitoba, Ontario, Quebec, New Brunswick, Nova Scotia, and Prince Edward Island. Bell swiftly identified and resolved the issue by 4:40 a.m., implementing a permanent fix later that morning.
Although the outage affected call routing in six provinces, the majority of calls were successfully managed by backup systems during the disruption. The missed calls, routed through older systems, did not lead to any critical public safety incidents, according to the report.
Bell, emphasizing its commitment to emergency services reliability, is investigating why early alarms failed to trigger a timely response during the outage. The company has since installed additional monitoring mechanisms to prevent similar incidents and is conducting a thorough review of its system.
To safeguard against potential security risks, Bell redacted specific details about the outage’s cause and system vulnerabilities in the public report, citing concerns about potential exploitation by hackers.
The 911 service in Canada is interconnected with regional legacy telephone providers, with Bell serving Manitoba, Ontario, Quebec, and the Atlantic provinces. Other provinces are serviced by different providers like Telus and SaskTel.
Holly Barkwell of the National Emergency Number Association (NENA) highlighted the resilience of Canada’s 911 system while acknowledging the inherent imperfections of technology. The CRTC has mandated the decommissioning of all legacy 911 systems in Canada by March 31, extending the deadline by two years in early 2025.
