North American League of Legends servers suffered connection issues across the board early in the morning on May 12, with many players experiencing spikes. Players who were in the process of playing on Summoner’s Rift or the Howling Abyss saw their in-game ping spike upwards hundreds of milliseconds at a time.
The server instability appears to be affecting players on North American servers, on both the east and west coasts of the continent. Ranked queues have been disabled as a result of the game’s server issues. Players in Europe and other portions of the world should not be affected by this current wave of instability.
In-game effects of the instability include constant disconnecting and reconnecting, champions unable to move, the inability to buy items in the in-game shop, and structures appearing to be intact when in reality they’ve been destroyed.
Riot has marked the situation as “critical” on their server status webpage, saying that they’re “aware of a problem causing players to disconnect from their games and have disabled ranked queues while [they] investigate.”
Update May 12 3:01am CT: Riot has resolved North America’s server instability issues, according to the League of Legends service status page.
