PokerStars has confirmed that Distributed Denial of Service (DDoS) attacks caused "temporary site outages" that forced the cancellation of dozens of tournaments on Sunday, including all six WCOOP Main Events.
All tournaments were paused as a preventative measure at around 8:00 p.m. (BST) yesterday, before being cancelled less than two hours later.
PokerStars confirmed that all affected players would be compensated, and in a statement said that their teams continue to work on looking after players who have been affected.
The site also announced that they intend to run all WCOOP Main Events on November 6, ensuring a 2022 WCOOP Main Event champion will be crowned.
