Delta Grounding

Delta grounded all its flights worldwide yesterday claiming a power outage in Atlanta caused the system to go down. The power company said when the Delta systems went down, it took down the power. Still others speculated that it might be a hack. Dwayne Melancon, CTO at Tripwire commented below.

Dwayne Melancon, CTO at  Tripwire:

 “I have heard that the cause was a fire during a cutover to backup generators, which seems plausible. Furthermore, Delta has consistently claimed (including a statement by Delta’s CEO)  that this incident was the result of a power outage.If this were caused by a hack, I’d have expected someone to claim responsibility for the incident early in the process, which didn’t happen. Also, once the systems were back online, they seemed to work properly which lends credence to the claim that this was a power outage.  Of course, it is possible that someone attacked the power systems themselves, but I haven’t seen any credible evidence to support that theory.”
