The local power company, Georgia Power, said that their power had stayed on all night. Delta admitted that a "power control module" (which might be anything) failed early Monday morning and crashed their computer system, shutting down Delta flights world wide. And apparently rebooting the world wide systems isn't working so well. Delta is announcing further flight delays and cancellations for tomorrow.
Delta clearly needs to decentralize their computer systems, preferably down to the local airport level, so that a failure only knocks out ONE airport, not the entire world. The only thing that has to be centralized is the airline's seat reservation system. Agents sell seats all over the world. Before an agent can sell a seat, he has to know that the seat in question is available, not already sold to someone else. So all the seat sales go to the central computer system, which keeps track of which seats on which flights are available and which are sold. This function has to be centralized. But a lot of other stuff, like running the airport kiosks ought to be local.
Good luck Delta IT dept. You gotta lotta work to do, and a lotta flak to catch.
