Without backup plans, global IT outages will happen again

Elements of Friday’s global IT outage, which grounded planes and hit services from banking to healthcare, have occurred before and until more contingencies are built into networks, and organisations put better back-up plans in place, it will happen again.

Friday’s outage was caused by an update that U.S. cybersecurity firm CrowdStrike pushed to its clients early on Friday morning which conflicted with Microsoft’s Windows operating system, rendering devices around the world inoperable.
