Facebook for android missing?!!?

I uninstalled Facebook on my android Optimus v phone because it was defective. I was planning on installing it again after I did that. I go to install it and it's absolutely gone from the market. I've tried every name it could have on the market and it still wasn't there. I also went online to the market website on my phone and it still doesn't work!! I also tried going on the facebook mobile site and try and find the download app button at the bottom and its not there. How do I get the app back!? Please help me!!! Thank ya! :)
