Paulo Outubro começou with an unexpected event: no second-fair, logo após or time do almoço no Brasil, lose or access the three most used social networks, Facebook, Instagram and WhatsApp <https://link.estadao.com.br/noticias/geral,apagao-do-whatsapp-o-que-causou-a...> . Ficaram inacessíveis ferramentas used by quase metade da humanidade. Whatever it has been or the reason for it remains, its effects were deeply felt - years that focused its activities on these platforms was devastating. The internet was conceived as an interlinking of thousands of highly distributed networks, avoiding a single point of failure. On a network, a site can be connected, an e-mail server can be switched off, an underwater optical cable can be broken, and in all these situations we will have impacts that will vary in intensity and affect your users differently. A gigantic platform as mentioned, meanwhile, concentrates on the same different services. Issuers, recipients and content is not the same ship and depending on the same centralized infrastructure. An important failure, which momentarily disables the platform, will uncontrollably reach all of your participants and their multiple communication expectations. Many times to participate in social networks and also soothing for day-to-day aggravations and ways to provide entertainment and distraction. Of course, when we go to the extreme of addiction, we become compulsively dependent on the interaction of networks in search of emotional gratification (in Admirável Mundo Novo, Huxley disbelieves or uses “soma”, a drug that traces happiness, to fun and carefree: "Soma é tão bom como o alcool ea religião, e sem os seus problems"). More platforms also operate as important information channels and, frequently, as environments in which professional activity is exercised. <https://link.estadao.com.br/noticias/cultura-digital,empresas-tem-dia-perdid...> . Or WhatsApp, for example, which comes as a substitute for commercial telephony, but only temporarily becomes an important form of instant communication. In comparison as an electronic mail, which is an asynchronous process where or dialogue follows a more pleasant rhythm defined by the availability of two interlocutors, the digital messages substitutes for telephony tend to assume the same synchronous behavior, where a message “pede” to be read and answered in short time. A lack of this type of message can therefore cause serious lapses in commercial and professional communications, even if it is a simple loss of information and entertainment. O ditto Portuguese that the title suggests reads that “quem tem um, não tem nenhum”. Ou seja, we depend on a specific service, sem alternatives, more time less time we will have to deal with your unavailability problem. This unavailability will be more critical to the service or service in question for use in daily professional activities. Logo, e de bom alvitre ter letters na manga for or in case of failures in important services. Finally, or mentioned, it seems that it would also serve perfectly for what happens technically in this case. Hair that is stored - and that seems critical - houve a concentration of critical servers such as DNS, which generates access rights, in a single network structure, a single “autonomous system”. When, for some reason, during a restructuring of the local network, or on the way to this autonomous system, it must be found on the internet, or the world passes not to locate other servers. And, to complicate matters, the three platforms were present together nessa unique rede… Sem redundância: “quem tem um, não tem nenhum”. * É ENGENHEIRO ELETRICISTA https://link.estadao.com.br/noticias/geral,apagao-do-facebook-mostra-falha-d...
