Riot Games will be moving the North American servers for League of Legends across the United States soon. This change could dramatically effect your playing experience.
In a post on LoL's forums, Riot revealed that they'll be moving the game servers from Portland, Oregon to Chicago potentially by the end of the month. It seems that the initial tests for the new location were successful:
We’re now ready to confirm that we’re planning to move all NA game server activity from our current Portland servers to our new Chicago installation within the next few weeks. Due to the many factors in play, we don’t yet have an exact date for the switch, but we’ll be back shortly with both exact timing and final details.
Riot chose Chicago as the new home for their game servers because its solid infrastructure and centralized location. They feel the new location will enable them to bring every North American player's ping under 80ms. More than half of the LoL players in the region are currently above that mark.
The main beneficiaries of the server move are players on the East Coast. They should have a dramatically lower ping than they do now, making it easier to make Yasuo or Lee Sin highlight reels. The downside, though, is that West Coast players won't have the stellar latency they're used to. Here's Riot's overview of the move's effects:
Still, Riot argues that overall performance will improve for all players thanks to the PoP hardware they've been setting up throughout North America. They're promising better stability and less packet loss thanks to this infrastructure.
The company is hoping that the server switch from Portland to Oregon will be seamless and result in zero downtime. The Portland servers will be kept as a backup in case anything goes wrong with the transition.
Once the Chicago servers are up and running, Riot will offer free transfers to players in the United States and Canada who are playing on other servers. For example, many players in Florida use the Latin America North server currently because they're based in Miami. Riot will send out emails with instructions on how to switch to the relocated North American server.
