To save you from the endless bla bla bla:
...concluded that one of the three composite overwrapped pressure vessels (COPVs) inside the second stage liquid oxygen (LOX) tank failed
...failure was likely due to the accumulation of oxygen between the COPV liner and overwrap in a void or a buckle in the liner, leading to ignition and the subsequent failure of the COPV.
.... corrective actions .. short term ... changing the COPV configuration to allow warmer temperature helium to be loaded ... long term, SpaceX will implement design changes to the COPVs to prevent buckles altogether
Next launch on January 8th.
