On the 17th of Feb some form of Power Failure occurred at one of VMware's Palo Alto locations. From what I understand this primarily affected the support systems and as such the phones were down for most of the day.
Update 18 Feb 10 @ 8:28pm:
@vmwarecares Network outage here caused by small plane crash in Palo Alto
VMware Support back and up and running by 9pm CST.
