Problems with Adding Facebook Pages?

[-Autumn in the City-]

I've added a couple of Facebook pages for TV shows and, most recently, several Heath Ledger memorial pages and band pages, and they keep disappearing. Even when I search for them again, they don't show up.

Does this happen to anyone else? Anyone know why it's happening? I can't tell if I was blocked from the page (I haven't posted anything disrespectful) or if there's too much traffic...

Thanks in advance for any replies.

Yes. This happened to me too. Especially heath ledger related pages.I guess it's either they are over crowded or maybe it's a side effect to some maintenance issue on facebook...
