Industry committee  It's very difficult to simulate the live full environment. It can be parts. Because this was the sixth time we had done this and in the previous five times there was never an indication of any issue, this was a very unique case in the way one particular manufacturer designed their system and how it handles flow control and traffic.

Industry committee  All carriers use, and have used for many years, the concept of a common IP core. The common IP core is what's at the root here. A common IP core is obviously designed for security purposes. It lets you manage, and essentially I would describe it as the brain of the network. It's not something that traditionally is regionalized.

Industry committee  I'd maybe just add that the instances are very different. The instance on July 8 was essentially the core of the network, the brain of the network, that supports all wireless, wire line, internal communications and connectivity. It was a complete loss of connection. With the technical issue on the 911, as much as our fellow operators all offer to help, there is no technical way, with loss of connectivity....

Industry committee  First of all, the events are very, very different. Let me speak to the event of July 8. The way to characterize it is that there was no way for the engineer at the time.... When it had been performed five times prior with no incident whatsoever, there was no belief, no information at the time, that there was going to be any issue.

Industry committee  The April 21 outage was a software update performed by our partner. The software update in that instance was tested, but the nature of the way it was deployed caused the impact. That was done by our vendor. It was tested. It had been deployed in other networks around the world. It was an instance that the particular dynamic of the way it was deployed caused the incident in April 2021.

Industry committee  What we have tried to do is.... In our disclosure in response to the questions from the CRTC, we have been totally transparent in explaining...because what's so important from this is not just to Rogers, as the design of a common IP core is the consistent architecture used by operators all around the world.

Industry committee  This was an unprecedented impact to what's called the “core” of the network. The core of the network you can think of as the brain of the network that controls all access of flow of information and flow of connectivity for all services to the Internet. We have extensive...over two years in this particular program, with full rigour, full review and full analysis that was done.

Industry committee  That's correct. We do. We do both extensive simulation and extensive testing. We also rely heavily, side by side, with the equipment vendors who work with us. As we design and as we test, the equipment vendors work right alongside us. They provide the same infrastructure to all operators around the world, so we also gain the benefit of the learnings of all other operators in terms of how they've executed and how they implement.
