An outage affecting 911 services in multiple Canadian provinces for almost 90 minutes last month was attributed to an unnoticed bug 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 Manitoba, Ontario, Quebec, New Brunswick, Nova Scotia, and Prince Edward Island.
The report clarified that the disruption was not a result of a cyber attack or any planned or unplanned modifications. Philippe Gauvin, Bell’s assistant general counsel, explained that the outage was triggered by a “latent software issue” within Bell’s advanced 911 system, known as NG9-1-1, which enables the public to provide detailed emergency information for better response coordination by authorities.
Bell successfully identified and resolved the root cause, restoring service at 4:40 a.m. The company later implemented a permanent solution to prevent similar incidents. Although the outage affected call services in six provinces, backup systems managed the majority of calls during the disruption, with no critical public safety incidents reported due to missed calls.
Following the incident, Bell acknowledged the importance of uninterrupted 911 services and assured measures were in place to prevent future occurrences. The company’s prompt response to the outage was highlighted, emphasizing its commitment to enhancing emergency calling services for the public.
The report also revealed that early alarms failed to trigger a crisis response during the outage, with engineers only alerted after a separate alarm system detected a drop in incoming calls. Bell is investigating the alarm system failures and has implemented additional monitoring mechanisms to enhance system reliability.
For security reasons, specific details regarding the software flaw and system operations leading to the outage were redacted in the public report. Bell emphasized the need to protect the 911 infrastructure from potential exploitation by cyber threats.
In Canada, 911 services are managed by regional legacy telephone providers, with Bell overseeing services in several provinces. The incident underscored the resilience of the nation’s 911 system, with ongoing efforts to improve technology and ensure reliable emergency response services.
