Comments disappearing without being posted, no preview option

For the last few days, I've been almost completely unable to post on Jezebel. I hit the "submit" button and the comment just vanishes without being posted. For some reason, if I keep trying and refreshing the page, it'll work once in awhile, but nine out of ten times my comments are eaten without getting posted. Jezebel has worked just fine in the past and I'm disappointed. I haven't tried on other sites, but I imagine it's the same.

This morning, I'm also missing the "preview comment" checkbox. Cleared cache/history--this didn't help.

Please respond, Gawker Tech.
