Having too many outages wasn't listed in the risk factors of Facebook's filing, so they're probably not too concerned about it, but they do happen sometimes.
In fact, some people have been tweeting about Facebook downtime today, less than 24 hours since the filing was made public (hat tip: NY Daily news).
Facebook's been down for 15 minutes and I'm freaking out because I don't know if anyone's having babies, eating food, eating babies, etc. 🙁
#Facebook down!Signs of an IPO party hangover?
Facebook down? DId someone in legal over-interpret the SEC "quiet period" rules?
It's a good thing there's a Twitter. It never goes down.
