What's Up? RedFoo -- WhatsApp Outage is Screwing My Biz

WhatsApp has been down all day and RedFoo, and the singer says it's totally messing with his business -- so he's taking his patronage elsewhere.

WhatsApp was down for more than three hours on Saturday, coincidentally just days after Facebook bought it for $19 billion. However, the outage is supposed to have been caused by a router problem, which cascaded down through a bunch of servers.

WhatsApp Messenger is a proprietary, cross-platform instant messaging subscription service for smartphones, which is available for Google Android, BlackBerry OS, Apple iOS, Symbian,  Microsoft Windows Phone, BlackBerry 10, limited Nokia Series 40, and limited on the Nokia Asha platform.

On Thursday, February 19, 2014, Facebook announced it is acquiring WhatsApp for US$19 billion, and will pay $4 billion in cash, $12 billion in Facebook shares and an additional $3 billion in restricted stock units to be granted to WhatsApp's founders, Jan Koum, Brian Acton, and employees that will vest over four years subsequent to closing. The transaction is the largest purchase of a company backed by venture capitalists ever. Previously venture capital financial analysts valued the business at almost $1.5 billion.
