Why won't my iPad let me go to facebook?

[Chastity]

I'm on my iPad and I was on Facebook earlier today on safari and now ,when I try to connect to facebook it loads but it just stays on the blank white screen. I've tried doing it over and over I even cleared my search history and turned my iPad off and it does the same thing. I can go to other websites like tumblr and twitter with no problem but when I try to go to facebook it just has the blank screen. And on the tab for Facebook it has a little lock on it. Why won't it let me go to facebook and how can I fix it?

This happens every now and then, don't despair it will soon return, obviously the site is down for maintenance or updates I suspect! Mine won't load either!
