The July 8 Rogers outage affected the company's mobile and internet users and crippled several ATM services.
Rogers Communications says it was unable to route calls from its customers through its competitors during the major outage that affected its service earlier this month, despite offers of support from Bell and Telus.
This information provides insight into the solutions Rogers considered during the widespread outage that paralyzed the company's networks and affected millions of customers across Canada, including hundreds of thousands in the Atlantic.
In a brief presented Friday evening to the Canadian Radio-television and Telecommunications Commission (CRTC), the telecommunications giant also indicates that it has been unable to close access to its radio network, which could have allowed its customers to call 911 through another provider.
It was unable to route its customers' calls through its competitors because parts of the central system that would have allowed it to do so were affected by the outage. This also explains why it was impossible for him to close access to the radio network.
Rogers' recent outage, a second in 14 months, continues to make waves.
Rogers argues competitors would have been unable to deal with the finish sudden surge of millions of wireless subscribers. They would have been overwhelmed by the influx of a large volume of calls and data transfers.
The company says it was able to route thousands of calls to 911 during the outage. However, it is not known how many customers were unable to reach the emergency call service.
Rogers customers have made emergency calls using Bell or Telus networks.
The Canadian Radio-television and Telecommunications Commission (CRTC) had given Rogers until Friday to explain the cause of the failure, the extent of the problem, and the steps taken to prevent a similar problem from happening again.
Much of the information provided at the CRTC have been redacted for safety and competition purposes.
Rogers also indicates that four alert messages, all in Saskatchewan, could not be broadcast during the outage. One was an RCMP warning of a dangerous person on the loose and the other three were an Environment Canada warning of a tornado.
