But most of those are barely relevant to today's world; not just that the technology has changed, but that we didn't *have* a DR plan, and relied on the good graces of IBM and (the then monopoly) Bell telecom to get us on the air temporarily. It was a lot of fun in its way, everyone learned a lot, and our ops manager dined well at SHARE and other places where he gave his fire slides talk for several years after. Certainly one now blindingly obvious thing we learned that hadn't really entered anyone's head at the time is that DR is at least as much a business and organizational problem as a technology one. For instance, in those days before mobile phones, and when the closest thing to email ran on the down mainframe, where do you *go* when your office building is surrounded by fire trucks and a lot of yellow tape and fast-freezing water, and there is no one to answer any of the work phones? Anyway - the old stories are probably more of a Friday topic than anything very useful in 2017.
