Facebook account is temporarily unavailable due to site maintenance?

The site is working but I cannot log on, it gives me this message: Your account is temporarily unavailable due to site maintenance. It should be available again within a few hours. We apologize for the inconvenience.|||OMFG!! Hang in there, you'll be ok. Sh!t happens|||It's exactly what the message says. Facebook stores the web page and your account information on two different sets of computers. They had to turn off the computer with your account information to fix something or update something. You'll be able to access your account in a little while, once they get that machine turned back on.|||It does this occasionally - just wait and revisit your account later on. When Facebook makes changes, it does so in batches rather than all the accounts at the same time, so your account is just one of those currently being updated.
