Just curious, wouldn't it have been wiser to put the failover servers somewhere in the Midwest? It's pretty much as far away from the ocean as one can get, making tsunamis/hurricanes/etc. irrelevant, low earthquake risk, and a shorter flight from NYC. Seems a little inadvisable to place the infrastructure in two coastal areas; I guess it's probably about the local talent pool.
Yeah, Oregon is known for it's viscous tsunamis and earthquakes. Also if a tropical cyclone hit Oregon it would not be a hurricane, it would be a typhoon. http://www.diffen.com/difference/Hurricane_vs_Typhoon I think the idea of the second data center is that it is far away from the first one.
I think you got confused about the "NE Pacific Ocean" thing under the Hurricane column. The NE Pacific Ocean is the part of the Pacific Ocean that Oregon is on.
It would technically be an extratropical cyclone, but it would likely have started as a tropical hurricane off the coast of Mexico.
