Facebook is down

Nope, it's not.

Had several friends there saying they were having trouble this morning.

Well, it's definitely doing something odd for me, where I get the white screen after login. This persists even after clearing cookies/cache, or using an incognito browser instance. Help articles on FB go to white screen as well if you are logged in (clearing cookies will allow them to load). Maybe something to do with some authentication layer?

In any case, it's particularly annoying since I'm trying to use it to stay up to date on the fires a couple miles from me, and the eyewitness posts are useful.
