Ask HN: Is anyone else having significult difficulty posting right now?

I just spent a few minutes trying to submit a comment. After submitting, I would end up on news.ycombinator.com/r with a blank page. I assume there is some post-POST redirect that is failing to be sent, but the comment doesn't even seem to be being submitted. Similarly, I tried to edit the same post, and got sent to news.yc.com/x without updating the post.

I've noticed the whole site is a bit slow today. Are there significant server issues occurring?

(Sorry for the meta post.)
