There's always the “putting all your eggs in one basket“ vulnerability you have to gauge, and I would address this in two ways. Our enterprise data centres are truly 21st century data centres. We have begun to take people on tours in our enterprise data centres to help drive this point home. When they come from their departments, what we ask them to do beforehand is visit one of their data centres, some of which go back to the 1950s, and then come and take a look at ours. The difference you'll see are various types of passive defences on the outside, double walls that are heavily reinforced, all sorts of security protections, etc. From a physical standpoint they are solid defensible structures.
The other part of this is that we continue to revisit our strategy. IT is a very dynamic environment. You don't set a plan once and then stay the course for 20 years.
One of the things we are taking a look at is the point you were alluding to, which is our sustainability. In this day and age, we may not be looking at bombers coming across the horizon, but there are threats out there that are determined, and a small group of people could do a lot of damage. We don't want to have a smoking hole incident that cripples the government, so we are looking at what I refer to as “the bunker”. This is not something that's documented yet. We're still in the early stages. Our data centre team is looking at options, but it's this idea that of the data centres we have, there will be one that is bulletproof and a hole-in-the-ground kind of thing. We would back up the most critical systems from the other data centres to make sure if something really bad happens to most critical systems, we can still cut cheques, we can still collect revenue, and we can still govern and provide those services to government.
That's something that is a work in process, but what I can say is the data centres we are moving to are absolutely 21st century world-class data centres, and we invite the tours.
