There are many indications that the fault of Facebook’s global failure lies in the malfunctioning DNS servers, whose main job is to manage internet domains and replace site names with IP numbers. However, specialists point out that the real cause may lie elsewhere and may be behind the acronym BGP.
BGP stands for Border Gateway Protocol. It is a network protocol used to exchange routing information held by high-level Internet autonomous systems.
The problem may be that if the DNS server fails and there is a lack of BGP routes (which determine the paths to nodes of the world’s largest social network), such global failures occur.
Also check:
And apparently there are no such routes, because all the routes developed by the BGP protocol, which determine the paths to the servers of Facebook, simply had to be deleted as a result of errors made during the setting. update the tables containing them. Whether this is the case will likely be shown by the survey announced by the folks at Facebook.
According to Cloudflare, the failure of Facebook and other services was removed just before midnight PST. So it lasted a little over six hours. So far, this was the longest incident of its kind in the history of this social network.
