As did many users this morning, I tried to login to Facebook this morning only to find the message displayed on the right - sorry, we're down for maintenance. I've been too busy in the last couple of days here at the conference to go onto Facebook, but I've seen a number of messages on Twitter that people have been having problems getting into the site over the past couple of days
Given that Facebook wants to be the "social operating system", the question is - what is their plan for being available? Are they having scaling issues? If people come to use Facebook as a communication medium, what plans does Facebook have in place to ensure that it is available when people want to communicate?
