"Customer of Betfair and PokerStars have been left enraged after the software of both gambling giants suffered from major connectivity issues over the weekend.
Betfair’s sportsbook, betting exchange and websites were unavailable for more of April 13 after the firm’s servers came under attack from a Distributed Denial-of-Service (DDoS) attack. Betfair’s customer service team, manning the @BetfairHelpDesk Twitter account, confirmed to customers that a DDoS attack was the cause of the problems and reassured worried punters that their details and funds were safe."
