Power failure, clearly their back power systems are inadequate. I believe some of Delta's systems are also backed by SABRE which while ancient is generally rock solid (it lives in a nuclear hardened bunker in Tulsa). This problem is in Delta's own systems not SABRE.

the main host of delta is not sabre, it is deltamatic, a homebrew system that is run by delta. Most other airline systems like sabre communicate via teletype to one another

  I think the reservation system is SABRE, and likely they contract for some of SABRE's other services like crew scheduling, but other parts are pure Delta.

    Delta uses Worldspan as its GDS, not Sabre.
