A few hours later, Roskomnadzor confirmed the failure of MegaFon's infrastructure. 

Later, Russian media reported the real reason for the lack of communication and Internet access - "an effective carpet DDoS attack on MegaFon. The company itself said that its network was supposedly working "normally" but that possible access problems were due to reasons beyond their control.
