Facebook suffered a first in its history on Monday, October 4th and became inaccessible for hours. Billions of users from all over the world have had difficulty connecting to Facebook and its Instagram and WhatsApp.
Users who could not communicate with each other subsequently flocked to Twitter and showered Facebook with criticism. The social media company, which quickly published blind statements on this situation, explained how the event started with a blog post it published two days after the event.
The company’s vice president of infrastructure announced
According to the statement of Santosh Janardhan, the company’s vice president of infrastructure, the outage started with routine maintenance. The vice president announced on Sunday, October 3, that Facebook has issued a command to assess the usability of the backbone network that connects all its computing facilities.
As of this release, the command did not work properly due to a bug in the company’s internal control system. Thus, the problem, which did not work as expected, caused an outage that affected the whole world.
Facebook’s DNS servers were unable to obtain routing information for the border gateway protocol server users need to connect to, as they were unable to connect to the company’s primary data centers. As a result, users could not access the applications.
Janardhan explained the problem: “As a result, our DNS servers became inaccessible even though they were up and running. This made it impossible for users on the internet to find our servers.
Mentioning that the engineers physically deal with the error since the situation cannot be resolved remotely, the vice president underlined that the DNS problem also creates a problem in accessing data centers.
