Why Did The Biggest Crash In Facebook History Occur?

Facebook and all its services such as Instagram and WhatsApp will be in serious trouble since this evening. access problem it arose. During the access problems that continued throughout the evening, users could not access any of these services.

Making a statement on the subject, Facebook did not make any explanation as to the cause of the situation, while expressing that they are working to solve the problem. This brought with it all sorts of allegations. some Saying that Facebook was hacked some claimed that some technical errors were at the root of the problem.

The problem may be due to errors in BGP and DNS servers:

While such agendas are still hot and official statements have not yet been made, any justification can only be explained. a claim We need to know that it is. Because at such moments, it is possible to come across a lot of information pollution around. However, of course, every claim is not just a disinformation, some claims are quite strong.

One of the strong claims we’ve come across is that the company behind Facebook’s historical collapse tonight. On BGP and DNS servers claiming to have made mistakes. The source of the claim is CloudFlare vice president, Dane Knecht.

Knecht said in a tweet that Facebook’s DNS servers crashed and BGP (Border Gateway Protocol) He said it was disabled. The key point here is BGP. BGP, which is an advanced routing protocol, allows sharing and sharing information between autonomous systems on the internet. network protocol for routing and all the searches we do on the internet are basically done through this protocol.

However, if BGP is disabled, no action can be taken on the system in question, Facebook will not be able to handle it in such a scenario. inability to access their DNS servers means. This is the kind of ‘technical failure’ that could cause this great collapse we are experiencing. It is said that what caused this malfunction was a mistake made by Facebook engineers during a configuration. To remedy the situation, data engineers need to physically interfere with the routers in question. However, the inability of the employees to enter the center naturally causes the process to be prolonged.

In this context, we can explain the Facebook example as follows: Without BGP routing to the Facebook network, Facebook’s own DNS servers cannot be accessed. Likewise, Facebook-owned Instagram, WhatsApp and Oculus VR are also inaccessible.

The truth of this claim and the reason behind the collapse will only be finalized when Facebook makes an official statement. However, besides the hacking allegations, we can say that this is the most logical explanation so far.
