“We are registering what is in fact a cyber-attack on our information centre,” the commission’s secretary, Maya Grishina, said.
The commission’s website was attacked soon after voting began. A distributed denial-of-service (DDoS) attack peaked between 2am and 5am on Sunday, chairperson Ella Pamfilova said.
The attack originated from 15 countries, according to Pamfilova.
