The World Playoffs for League of Legends, which had been livestreaming just fine, have been called off after serious network problems plagued the latter stages of the competition.
After games were paused and disconnected all afternoon, developers Riot Games decided to play the remaining matches in the tournament at a "secured location" later this week.
That use of the term "secured location" is interesting, seeing as many in the LoL community believe the outages to be the result of outside interference like DDoS attacks, rather than simple network hiccups.
I've contacted Riot Games for comment on the delay and move, and will update if I hear back.
UPDATE - Riot's Chris Heintz tells Kotaku:
We have no reason to believe there was any outside interference or foul play at this time.
Internet issues both local and upstream; our network guys are continuing to investigate root cause.
By secure we meant more stable - we'll make announcements soon.
UPDATE 2 - The official League of Legends site has posted the following statement:
After a series of connectivity issues at our LA Live venue, we've had to reschedule the final games of the Season 2 World Playoffs. We'll be completing the last game of the CLG EU and Team WE quarterfinal match and finishing out the Semifinal Matches in the near future from a new location with a secure Internet connection. The matches will be broadcast live, so stay tuned for scheduling information.
We apologize for the inconvenience, and want to thank all of you for your patience. It wasn't our intention to disrupt your viewing schedules, but the situation is unavoidable, and — in the interest of doing what's best for your favorite teams — we want to ensure we're not subjecting them to frequent disconnects.
Thanks for sticking with us, summoners. We hope to see you all online for the Semifinal matches. Stay tuned for more information.
