number of weeks our financial system will be down: 4-6
number of weeks our computer network will be partially down: 4-6
Infrastructure! Gotta have it.
Of course, in a *real* industry, they would presumably spend money on keeping a second
backup financial system running while the main one is down, and on renting new
office space with intact computer networks while our building is being upgraded.
In the absence of resources for doing that, we will just do the best we can to work around it.
