Irish Lottery suffered a distributed denial-of-service (DDoS) attack that knocked its website offline and made it inaccessible to gamblers for some hours back in 2016.
The attack also disrupted the ticket purchase as 3,500 ticket terminals also stopped working amid the attack.
However, National Lottery’s DDoS protection systems limited the disruption and restored all operations within two hours preventing the attack to cause more harm.
