SpaceX, Facebook page down after Musk promises on Twitter

Rocket company SpaceX's verified Facebook page disappeared on Friday, minutes after its founder and Silicon Valley billionaire Elon Musk promised on Twitter to take down the page when challenged by a user.
"Delete SpaceX page on Facebook if you're the man?" a user tweeted to Tesla Inc chief Musk. His response: "I didn't realize there was one. Will do."
SpaceX's Facebook page, which had more than 2.7 million followers, is no longer accessible.
Musk had begun the exchange by responding to a tweet from WhatsApp co-founder Brian Acton of the #deletefacebook tag.
"What's Facebook?" Musk tweeted.
