         | code will be hit.
         | 
         | The WhatsApp servers will be sitting idle most likely!

           | 
           | Seems much more likely to me that WA/IG/Oculus somehow rely
           | on facebook.com behind the scenes than that all FB domains

         | I worked at WhatsApp until Aug 2019. WhatsApp hasn't been on
         | completely separate infrastructure for quite some time. It's in
         | FB datacenters, so if FB BGP is messed up, so is WA. There is a
         | separate WA ASN that's used for DNS, but it's still FB infra,
         | and announced through the FB ASN, so that doesn't help either.
         | Instagram still has their DNS with AWS Route 53, so their DNS
         | is still up, but their site isn't because it runs on FB Infra
         | too.
         | 
         | Within the FB datacenters, WhatsApp is somewhat isolated (at
         | least when I left, chat was run on dedicated hosts allocated to
         | WhatsApp only, but using FB container orchestration tools, and
         | FB specified hardware, etc).
         | 
         | Edit to add: WhatsApp has some mitigations against DNS not
         | working, but in this case, it looks like DNS being dead was a
         | symptom of something (probably BGP config error, if the Reddit
         | post earlier was accurate) and that something also broke the
         | underlying servers.
