The world is temporarily a better place with Facebook, WhatsApp, Messenger, Oculus VR, and Instagram being inaccessible right now. Twitter, unfortunately, is still operating, but at least people are posting some funny memes about it!

Cloudflare senior vice president Dane Knecht notes that Facebook's border gateway protocol routes — BGP helps networks pick the best path to deliver internet traffic — have been "withdrawn from the internet."
Those pesky border gateway protocol routes!
