An unexpected software glitch in Bell’s system caused a 911 outage lasting around 90 minutes across multiple Canadian provinces last month, the company revealed in a recent report. The disruption, which occurred at 3:13 a.m. ET on Sept. 17, impacted Manitoba, Ontario, Quebec, New Brunswick, Nova Scotia, and Prince Edward Island.
Bell clarified that the incident was not a result of a cyber attack or any planned changes. The bug affected components of Bell’s advanced 911 system, known as NG9-1-1, aimed at enabling the public to provide detailed emergency information to dispatchers for more effective response by emergency services.
Service was restored at 4:40 a.m., with Bell implementing a permanent fix later that morning. The company assured that the majority of calls during the outage were managed by backup systems, although some traditional voice calls were missed if directed to a call center utilizing outdated systems.
Fortunately, none of the missed calls led to critical safety issues. Bell declined to disclose the number of missed calls but emphasized its commitment to continuous enhancement of emergency services.
Additionally, the report highlighted that initial alarms at the onset of the outage failed to trigger a crisis response promptly. It wasn’t until a separate alarm system detected a drop in incoming calls that the response team was alerted, leading to the resolution of the issue.
Bell is investigating why the alarms failed and has implemented additional monitoring measures for enhanced reliability. The company is conducting a comprehensive review of the system and sharing insights with other service providers.
Specific details about the outage cause and broader system information were redacted in the public report to prevent potential exploitation by hackers. Bell emphasized the importance of safeguarding the 911 network against vulnerabilities.
In Canada, 911 services are managed by regional legacy telephone providers, with Bell covering Manitoba, Ontario, Quebec, and the Atlantic provinces. While technology issues can arise, efforts are ongoing to ensure the resilience and effectiveness of the emergency response system.
The CRTC has mandated the decommissioning of all legacy 911 systems in Canada by March 31, with a recent extension granted until 2027 to facilitate the transition to advanced emergency technologies.
