Marcelo,

Esse mesmo alerta também foi comentado em outras listas. O pessoal do
BGPmon publicou no twitter [1] que detectaram alertas para mais de 400k
prefixos.

O volume de atualizações de anúncios deste AS [2] desde 18h até 21h UTC
também indica que "alguém configurou algo errado"...

Abraços,
Gustavo.
