Facebook Meltdown?

So, um, Word Challenge was getting sort of sluggish and I rebooted, figuring it was my pathetic browser (Camino), which periodically just quits for no good reason, or my own lack of internal maintenance duties on my Mac laptop, which I've had for two years and managed so far to avoid even reading the instructions, much less take the online course.
But nooo, me and gazillions of other users are told this:

Account Unavailable

Your account is temporarily unavailable due to site maintenance. It should be available again within a few hours. We apologize for the inconvenience.

Excuse me, a few hours? Guys, this is the internet. If it ain't instant, it's dead to me.
Oh, wait. Maybe it's the increased traffic from the earthquake in Italy. Nah, not big enough news to swamp the world's leading — and so far unprofitable — online whatchamacallit.
Virus? What ever happened to that April Fool's thingie that was supposed to end civilization as we know it.
Whatever. Thing is, how has this affected Wall Street?
Maybe cyberterrorism. North Korea has penetrated the Net, the Web, whatever. Or AQ. I was for years convinced that Richard Clark's account of the weaknesses in the system was an indicator of things to come. But they never came. What terrorist can live without the Net these days?
UPDATE: Okay, it was less than an hour. Still.
