#Facebook Outage Appears to be a DNS Hack
According to Internet security researcher Brian Krebs (@briankrebs),
Confirmed: The DNS records that tell systems how to find Facebook.com or #Instagram.com got withdrawn this morning from the global routing tables. Can you imagine working at FB right now, when your email no longer works & all your internal FB-based tools fail?
To be more precise (and Geek Factor 5) the BGP routes serving Facebook’s authoritative DNS were withdrawn, rendering all Facebook domains inaccessible.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.
Domain Name Servers (DNS) are the most important thing on the Internet. It is like a phone book, where you type a name, and the DNS record says, oh, Facebook is here at this IP numerical address.
Without DNS records, Facebook and Instagram are DOA.
[UPDATE]
JUST IN – Facebook employees reportedly can’t enter buildings to evaluate the Internet outage because their door access badges weren’t working (NYT) #pathwaysradio
