...

... e continua.

Isso é algum tipo de ataque de DDOS (duvido muito) ou é normal obter essa quantidade de solicitações de ping?

Eu mencionarei que nosso provedor de internet nos classificou como "grandes gastadores" e agora somos forçados a navegar em banda estreita pelo resto do mês. Pode ser uma pergunta estúpida, mas pelo menos eu vou aprender alguma coisa.

Obrigado.

    

Answer 1

Neste caso, parece ser exatamente o que diz ser. Se você enviar seus logs para o ISP, talvez faça com que você seja restabelecido na banda larga, já que claramente não é o tráfego que você deseja.
