A recent 911 service disruption that affected several Canadian provinces for about 90 minutes was attributed to an unforeseen glitch in Bell’s software, as per a report released by the company. The outage, impacting regions including Manitoba, Ontario, Quebec, New Brunswick, Nova Scotia, and Prince Edward Island, began at 3:13 a.m. ET on September 17. Bell clarified that the incident was not a cyber attack but rather a result of a “latent software issue” within its NG9-1-1 system.
Bell promptly identified the software bug causing the problem and restored service at 4:40 a.m., implementing a long-term solution later that morning. The company acknowledged that the disruption affected services in six provinces, but most calls during the incident were managed successfully through backup systems. However, voice calls routed through older systems to call centers equipped with the new technology were missed.
Although the missed calls did not lead to any critical public safety incidents, Bell did not disclose the exact number of calls affected. Bell emphasized its commitment to the reliability and enhancement of emergency services, stating that steps have been taken to prevent such incidents from recurring.
The report also highlighted that early alarms during the outage failed to trigger an immediate crisis response as expected, leading to a delayed intervention by the response team. Bell is investigating why the alarms malfunctioned and has introduced additional monitoring mechanisms for improved oversight. The company is conducting a comprehensive review of its system, engaging call center staff in debriefing sessions, and sharing insights with other service providers.
To safeguard against potential security risks, Bell opted to redact specific information regarding the software flaw and broader system details in the public report. The company cited concerns that disclosing such information could expose vulnerabilities in the 911 infrastructure to potential hackers, jeopardizing public safety.
In Canada, 911 services are managed by regional legacy telephone providers, with Bell overseeing operations 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 to allow for a smooth transition to updated emergency calling technologies.
