During the epic match between FlyQuest and Cloud9League of Legends had to show the world some of their new technology. Riot calls it their "Terministic Disaster Recovery Tool" or "DDR" or simply "Chronobreak."

At the 10:47 mark of the match, Johnny "Altec" Ru's ultimate as Miss Fortune encountered a visual bug. It seemed as if his ultimate was blocked by a minion in front of him but the damage did indeed go through. Altec called for a pause shortly after and following a 30 minute break, the game rewound. 

After everyone went "woah" and Cloud9 went on to win the game, people wanted to know what exactly this new tool was. Riot has opened up and are more than willing to talk about their latest game changing tool.

What is Chronobreak?

"This new tool allows us to recover from disasters such as bugs during live events to maintain competitive integrity."

How long has it been in Effect?

"Since the start of Spring Split, we’ve had Chronobreak running in the background at the NA LCS."

So how does it work?

"Chronobreak saves a Server Replay of a game while it’s being played (a recording of all the inputs received by the server). If needed, the Server Replay can be used to create a new game and play it up until any point in the timeline. Players and Spectators can then connect to the new game and resume play."

tl;dr - You can basically scroll back in time to any point in the game and start again from there

Did teams know about this technology?

"Yes, NA LCS teams were informed about our new tool at the start of Spring Split."

When do officials know when to use Chronobreak?

"We’ll only use Chronobreak in a situation that would warrant remaking the game.  NA LCS officials evaluate bugs on a case by case basis, making sure that they are both Verfiable (proven to be a bug) and Critical (The bug altered the course of the game significantly)"

"Once NA LCS officials determine the bug meets the above criteria and a remake is accepted by the impacted team, NA LCS officials will attempt to use Chronobreak to recover the game prior to when the bug occured. If Chronobreak doesn’t work, a full remake will be implemented instead."

How many bugs does Chronobreak recognize?

"While Chronobreak addresses the types of bugs that cause more than 90% of remakes in competitive play, it does not address all of them such as the Aurelion Sol bug at Worlds 2016, which would have recurred even in a recovered game."
