I guess certainlyT is the reason the game servers are in Oregon

I'm aware they're moving to Chicago but they're currently in Portland Oregon

The most obvious issue with our current Portland game servers is their coastal location. While keeping the original servers near Riot’s west-coast offices made sense back when we were just starting out, both the exponential growth of the NA server and North America’s changing internet landscape mean that west-coast servers are now directly contributing to markedly inferior service for a huge number of east-coast players.
