On Monday evening, NetBlocks published a technical analysis of the possible reasons behind the failure of Facebook and its accompanying applications, Instagram and WhatsApp.
The website reported that an analysis of network measurements on October 4, 2021 indicates a global outage for Facebook Inc services, including Facebook, WhatsApp, Instagram and Messenger services since 15:45 GMT.
He said network metrics point to a connection outage on the Facebook-owned standalone network AS32934, adding that the most obvious impact is the loss of trusted DNS.
He noted that the root cause of the incident has not yet been fully identified, although there are indications that the Border Gateway Protocol may have been pulled or hijacked, causing an indirect impact on the DNS and other servers needed to resolve services.
The Border Gateway Protocol or Intergate Routing Protocol is an external routing protocol designed to exchange routing-related information between independent systems in computer networks.
The Border Gateway Protocol can be used as an internal routing protocol, in which case this use is referred to as the Inner Gateway Protocol (iBGP), and for the original use the External Border Gateway Protocol (eBGP).
Facebook has experienced international outages previously, including major partial outages on April 14, 2019 and March 14, 2019 however the current incident is the largest Facebook outage on record since its inception.

domain registration companies today listed the domain Facebook.com as up for sale. This happened thanks to automated systems that look for registered domains which appear to be expired, abandoned or recently vacated.
There’s was never any reason to believe Facebook.com would actually be sold as a result, but it’s fun to consider how many billions of dollars it could fetch on the open market.
