Delta Airline, the No. 2 U.S. carrier by traffic said “our systems are down everywhere.”

Planes have since started taking off again but not before wreaking havoc on travel plans around the globe


A power outage at Delta Airline’s headquarters in Atlanta early this morning has caused a global computer failure that halted all flights – stranding tens of thousands of Delta passengers around the world.
I keep being amazed and appalled at how centralized our computer systems have become -- and therefore how a single power failure or computer glitch can bring down an entire global system. Our economic system is simultaneously becoming more and more centralized. Fifteen years ago we had 12 major airlines; now we have just four.
This increasing centralization of computers and Internet communications, combined with increasing centralization of economic power, creates enormous fragility and vulnerability – not just to terrorism but to natural disasters and glitches. Digitization and the Internet were supposed to enable distributed systems – decentralized communications, small-scale sources of power, innovative small businesses, fail-safes of all kinds. We no longer depend on giant economies of scale. Yet we’re ending up with just the reverse: Massive centralization, which is outright dangerous.
What do you think?
