Lessons from high-profile IT failures

This summer's outages at Delta and Southwest have much to teach all of us in IT about disaster recovery and high availability

It has not been a good few months for the health and consistency of airline information technology. Two huge outages within a couple of weeks of each other -- caused by simple component failures -- resulted in massive passenger disruptions and cost two U.S. airlines millions of dollars in lost revenue and customer compensation.

These events, while of course most painful for those who experienced them, present quite a few opportunities for learning and improving our own processes, and that's what I'd like to explore in this piece.
