Tenho um problema ao atualizar o Linux. Recebi um 404 não encontrado para o IP do servidor de destino, o que foi estranho o suficiente. Mais tarde, descobri que o traceroute passa por um nó backbone.rt.ru do núcleo.
Isso é um possível sequestro de BGP?
Os domínios ru hoje em dia parecem muito suspeitos, especialmente na Europa Central.
