A recent 911 service disruption that impacted multiple Canadian provinces for about 90 minutes was due to an unforeseen bug in Bell’s software, according to a report released by the company. The incident was not a result of a cyber attack or any planned changes, clarified Philippe Gauvin, Bell’s assistant general counsel, in a communication to the Canadian Radio-television and Telecommunications Commission (CRTC).

The glitch affected components of Bell’s NG9-1-1 system, intended to enhance emergency response by enabling the public to provide detailed information to responders. Bell swiftly identified and resolved the issue, implementing a permanent fix shortly after service was restored. The outage, which occurred early in the morning, impacted service in six provinces.

During the disruption, most calls were managed successfully by backup systems, although some legacy voice calls were missed if they were directed to call centers still using older technology. Fortunately, none of the missed calls resulted in critical public safety incidents.

Bell, emphasizing its commitment to emergency services reliability and improvement, mentioned that the September 17 incident was the first of its kind since the NG9-1-1 system launch in early 2022. The company declined to disclose the number of missed calls but assured that measures have been taken to prevent similar incidents.

In a related development, a report highlighted that initial alarms at the start of the outage failed to trigger a crisis response promptly. Subsequent investigation revealed lapses in the alarm system’s functioning. Bell is actively reviewing its monitoring mechanisms and conducting a comprehensive system evaluation to prevent future disruptions.

The report also mentioned that disclosing specific technical details could pose security risks to the 911 infrastructure. Bell redacted sensitive information to safeguard against potential exploitation by hackers.

Despite the resilience of Canada’s 911 system, occasional technological challenges can occur, as highlighted by Holly Barkwell, the Canadian region director for NENA. The CRTC has mandated the decommissioning of all legacy 911 systems in Canada by a set deadline, which was recently extended by two years.
