This is something that started happening a few days ago...:

Sometimes Flyertalk pages will take up to a minute to load, and occasionally fail to load altogether... all, according to the message at the bottom of my Firefox window, because of a slow response from ak.connect.facebook.com.

This is Flyertalk, not Facebook - and I think it's wrong that a non-responsive Facebook server should affect our ability to view Flyertalk pages. May I respectfully suggest that you look into ways of fixing this?
