Ask HN: Unable to post links to FB about the surveilance from reddit?

I tried posting the following link: http://www.reddit.com/r/changemyview/comments/1fv4r6/i_believe_the_government_should_be_allowed_to/caeb3pl

but when I try to click the link facebook returns a "Server error"

However when I post http://www.reddit.com/r/AskReddit/comments/1fvdc7/what_is_the_most_pointless_job_in_existence/

the link redirects fine. Can anyone else replicate this?
