Facebook, Instagram, WhatsApp still down worldwide after DNS records disappear causing Facebook.com domain to be listed for sale

Facebook, Instagram, Whatsapp, and Facebook Messenger, are have been down for several hours due to domain name system (DNS) issues. Internet researchers Brian Krebs confirmed the DNS issue in a tweet saying:

“To be more precise (and Geek Factor 5) the BGP routes serving Facebook’s authoritative DNS were withdrawn, rendering all Facebook domains inaccessible. That’s per @DougMadory, who knows a few things about BGP/DNS.”

The DNS records that tell systems how to find Facebook.com or Instagram.com got withdrawn this morning from the global routing tables. A search for Facebook’s DNS records comes up empty-handed as shown below.

“Can you imagine working at FB right now, when your email no longer works & all your internal FB-based tools fail?” Krebs asked. Facebook.com is now listed for sale, according to data from domain research firm DomainTools. Below is the screenshot.

In a separate tweet, NBC News’ Kevin Collier said the DNS issues at Facebook “really bad.”

“Don’t yet know exactly what’s behind the DNS issue that’s knocked Facebook/Instagram/WhatsApp offline, but it’s really bad. Pretty much everything that runs through those three companies are inaccessible. Employees can’t even enter conference rooms because they’re IoT!,” Collier tweeted.

Meanwhile, Facebook’s enemies are celebrating on Twitter. Responding to Edward Snowden’s tweet, one user said: “We don’t need to turn Facebook back on. Everyone on the infra group could just quit, and do nothing. I want to believe in that world.”
