Why does Google suddenly bring up the EU version of the site when I'm in NA?

So I don't always use the League site from my personal computer, and I can usually get to it by googling "League of Legends" and have done so for like the past year. It would always bring up the proper region's site - I'm in the US, so it would bring up NA's version of the site.

However, today, when I google "League of Legends," the google index is now suddenly bringing up the EUNE version of the site. What's going on here with your google indexing?
