Muito poucos de n\u00f3s no setor de hospedagem na web precisar\u00e3o escalar para o n\u00edvel que servi\u00e7os como o Dropbox fazem. Dito isso, quando um servi\u00e7o do tamanho do Dropbox d\u00e1 um passo em falso que leva a uma interrup\u00e7\u00e3o, vale a pena prestar aten\u00e7\u00e3o \u00e0s causas e ao impacto para ver se h\u00e1 li\u00e7\u00f5es em potencial a serem aprendidas.<\/p>\n

Em 10 de janeiro, o Dropbox ficou offline. Os usu\u00e1rios n\u00e3o conseguiram sincronizar suas pastas e, portanto, n\u00e3o conseguiram acessar seus arquivos em muitos dispositivos. O servi\u00e7o ficou inoperante durante grande parte da noite de sexta-feira e os usu\u00e1rios tiveram problemas para acessar seus arquivos durante o fim de semana.<\/p>\n

Of course, the media was full of speculation about potential causes for the outage, with many focusing on a possible DDoS attack. On the following Monday, Dropbox released a statement that went into detail about the causes of the outage, which dismissed the idea of an ataque de hackers<\/a> e culpou um processo de atualiza\u00e7\u00e3o com defeito.<\/p>\n

No dia da interrup\u00e7\u00e3o, o Dropbox estava executando um backup agendado do sistema operacional. Como voc\u00ea pode imaginar, atualizar os milhares de servidores que o Dropbox usa n\u00e3o \u00e9 uma tarefa f\u00e1cil. Grande parte do processo \u00e9 automatizado com scripts, que podem ter sido a causa do tempo de inatividade.<\/p>\n

A principal li\u00e7\u00e3o aqui, conforme detalhado pelo chefe de infraestrutura do Dropbox, Akhil Gupta, \u00e9 que, se voc\u00ea deseja fazer uma atualiza\u00e7\u00e3o, precisa ter certeza absoluta do estado do servidor. Para impedir que o mesmo erro ocorra novamente, O Dropbox implementou um n\u00edvel extra de verifica\u00e7\u00f5es, para que o servidor verifique seu pr\u00f3prio estado antes de executar comandos, em vez de executar cegamente as instru\u00e7\u00f5es recebidas, independentemente do que est\u00e1 fazendo quando as recebe.<\/p>\n

Isso n\u00e3o \u00e9 mencionado no post-mortem do incidente, mas a interrup\u00e7\u00e3o provavelmente poderia ter sido evitada com testes mais rigorosos. A interrup\u00e7\u00e3o do Dropbox \u00e9 um lembrete do que pode acontecer quando uma empresa est\u00e1 escalando rapidamente sua infraestrutura. Escalar se torna o objetivo principal e os testes caem no caminho at\u00e9 certo ponto.<\/p>\n

Uma abordagem mais rigorosa ao teste e verifica\u00e7\u00e3o de scripts de automa\u00e7\u00e3o pode ter detectado o "bug sutil" antes de causar estragos.<\/p>\n
