Bee on crying.
Last Sunday, a whistleblower by the Facebook misconception of the Facebook misconceptions, which was aired on the US news show program "60 Minet".As the Facebook stock goes down with the shocking content, this time goes down to the Facebook site.It has become an abnormal situation that "disappears" for more than 6 hours from the Internet around the world for the service and the underworld.
What was the cause of the large -scale disability?Let's look back easily.
It was around 8:40 AM on Monday on Monday, US West Coast.
対象は主にFacebookとInstagram、WhatsApp、Messenger、Oculus、Workplaceですが、Facebookでログインして『Pokemon GO』など利用している人たちにもアクセスエラーが表示され、みんなそろって再アクセスを試みたであろうことからネット全体がもっさりと遅くなり、アメリカ三大モバイルキャリアのVerizon、T-Mobile、AT&Tに｢つながらない！｣という苦情が殺到。
Disability status confirmation site "http: // isitdownRightnow.COM (which one is not down?) "
"I can't connect!" From all over the world, the media began to make a fuss, and Whatsapp recognized the system failure first, and immediately after that, Facebook was revealed that "we are working on early recovery."Because it has been down, it is unavoidable to announce it on Twitter), and a long and long day starts.
Despite the declaration of early recovery, the disability was not limited to outside the company, and the Facebook internal system was down.Internal Tools, WorkChat, Workplace, and Workplace Rooms are no longer available, and employees will suddenly switch to SMS and Outlook emails.
Employees who rushed to the headquarters to investigate the cause did not open the doors stubbornly even if they hold an employee ID card.
Eventually, a small number of elite teams were sent to the data center in Santa Clara near the headquarters, and it was manually combined with the server reset.
According to a security journalist Brian Cleb, he said to the religion of restoration, "The disability was due to the BGP (Border Gateway Protocol) regular update, but those who could correct it remotely were Apde.It has been blocked. The people who can access physically have no authority to access the network. Neither of them came out of recovery. "An absurd dilemma like the novel "Catch22".
Eventually, it is said that an angle grinder (a tool for polishing or cutting metal with a high -speed rotation disk) was introduced to secure access to the server cage.One angle grinder in one company.Maybe CTOs from all over the world are running to buy.
