••PNW Windstorm

––Winds in excess of 90 Mph (60+ Mph in Seattle)struck W. Wash.

––1 to 2 million homes/businesses lost commercialpower (majority for 48 to 72 hours)

––VZW Results:

••At worst point, 60% of our cells (including 2 of3 MSC’s) w/o commercial power - 87% ofsites were operational

••Network carried 50% more traffic than normalFriday

••Baseline results for 2 days following thestorm demonstrated VZW superiorperformance
