You may have gotten hacked and/or banned. Post the link to your profile. If other people can still see it, you're not banned.

Facebook is undergoing maintenance for their site. Some accounts go unavailable during that time and will be back up soon. Just like the message says. You'd know if you were hacked or banned because it will be gone completely and unable to log in.

Mine is doing it too. So i think it might actually be a site issue.

However i did manage to access it on my phone so im not banned and i doubt that you are

This does not surprise me very much as everyone recently (and longer before that) has been complaining that it NEVER works right.

FB should get its act together and provide a service that actually works because for all the money that they get paid for directing advertising directly at you depending on your likes and location they have NO excuse.

It's simply a maintenance thing with Facebook.

It's a pain in the butt, but it happens to pretty much all of us Facebook users.
