I found it interesting that this occurred right after Mercury (communication) squared the progressed Sun in the US chart at 1:53 am.  The computer glitch occurred between 5:15 am and 5:30 am, and by 9 am flights were being canceled just as the Moon was moving out of Sagittarius (air flight) to Capricorn (grounded on the earth).  Once the Moon moved into Capricorn at 10 am it was conjunct Pluto in Capricorn (transformation) and squared by Saturn (restriction, challenge).  

Probably just a coincidence, but interesting nonetheless!!
