Facebook, WhatsApp, and Instagram are down worldwide, it’s panic online

Users worldwide are experiencing problems while accessing Facebook services, including Instagram and WhatsApp.

Users worldwide are not able to access Facebook, Instagram, and WhatsApp services due to a BGP problems. Users attempting to visit the above services are displaying “DNS_PROBE_FINISHED_NXDOMAIN.”

The mobile applications of the social network giant and its Tor hidden services are also not working.

John Graham-Cumming, CTO at Cloudflare, reported that some minutes before Facebook’s DNS outage began they observed a large number of BGP changes for Facebook’s ASN a circumstance that suggests BGP routing problems.

About five minutes before Facebook’s DNS stopped working we saw a large number of BGP changes (mostly route withdrawals) for Facebook’s ASN. pic.twitter.com/dMTevg6hqj— John Graham-Cumming (@jgrahamc) October 4, 2021
Between 15:50 UTC and 15:52 UTC Facebook and related properties disappeared from the Internet in a flurry of BGP updates. This is what it looked like to @Cloudflare. pic.twitter.com/PFw5FR2W5j— John Graham-Cumming (@jgrahamc) October 4, 2021
Relax everyone. It’s October, the cyber-security awareness month and Facebook simply wants to make us aware of the cyber-security problems of the BGP protocol.— Vess (@VessOnSecurity) October 4, 2021
This one looks like a pretty epic configuration error, Facebook basically don’t exist on the internet right now. Even their authoritative name server ranges have been BGP withdrawn.— Kevin Beaumont (@GossiTheDog) October 4, 2021“We’re aware that some people are having trouble accessing our apps and products. We’re working to get things back to normal as quickly as possible, and we apologize for any inconvenience.” Facebook communications executive Andy Stone wrote on Twitter.
