Approx' time league will be back up?

I have the same problem too and I am very sad

Cannot login. "Server is busy". What happened?

They are basically making master yi very viable right now and i'm excited to play it. That new Deathbringer item will make yi so good, after hamming someone and you're low, either lifesteal to survive or W it. I'm so hyped

Well, Riot is being a fucked up piece of rat shit who doesn't care about the North American community apparently. LOLJK love you Rito <3 but still when the fuck is the server coming back up*[slayer-jinx-unamused]*

Edit: It had an estimated time of about 3 hours on the server status page.

Based on older big patches, it could be 4-6 hours.
