United Airlines, NYSE Outages Reveal Poor Redundancy Architecture, Insufficient Testing

Matt Gerber, CEO of Digital Fortress, a cloud services and data center operator based in Seattle, told CRN that for those failures to have occurred, the systems must have had shortcomings in built-in redundancy, fault tolerance and instantaneous failover capabilities, and they likely were not properly tested.
