Since I have neither interest in nor an account with Facebook, I learned of Facebook's BGP disappearance from world routing tables only a few moments ago - no Facebook, no Instagram, no WhatsApp; and for me, the entire event went unnoticed. I learned of this later through the intrepid hero, Edward Snowden.
Same day and another coincidence; completely unrelated, of course...
Deserves songs of praise, lyrics of three beautiful letters: F-J-B, F-J-B, F-J-B.
